The Effects of Trauma on Brain and Behavior The Effects of Trauma on Brain and Behavior BY ELI DEHOPE, PH.D., LCSW, BCD What is Trauma? Trauma results from an event or a series of events that subsequently causes intense physical and psychological stress reactions. The individual’s functioning and emotional, physical, social, and spiritual health can be affected. Trauma can be caused by a physical assault, emotional assault, developmental situations and environmental considerations THE KEY! UNDERSTANDING IS THE KEY TO WORKING WITH HUMAN BEINGS And what about the brain? DR. ELI DEHOPE Major Components of the Brain Brain Stem / Spinal Cord – Primal functioning – components to keep you alive Cerebellum – Basic functioning - coordination of movement, posture, and balance. Cerebrum – Higher functioning part of the brain - (lobes of the brain) DR. ELI DEHOPE PARIETAL LOBE ◦ Located behind the frontal lobe ◦ Concerned with perception of stimuli related to touch, pressure, temperature and pain. Parietal Lobe, Right - Damage to this area can cause visuo-spatial deficits (e.g., the patient may have difficulty finding their way around new, or even familiar, places). FRONTAL LOBE Parietal Lobe, Left - Damage to this area may disrupt a • Located at the front of the brain patient's ability to understand spoken and/or written language. • Concerned with reasoning, decision The parietal lobes contain the primary sensory cortex making, planning, parts of speech and which controls sensation (touch, pressure). Behind the movement (motor cortex), emotions, primary sensory cortex is a large association area that and problem-solving. controls fine sensation (judgment of texture, weight, size, shape). • This area determines personality and allows for us to create relationships • Called THE BOSS! DR. ELI DEHOPE TEMPORAL LOBE ◦ Located to the side of the brain ◦ Concerned with perception and recognition of auditory stimuli (hearing) and memory (hippocampus). There are two temporal lobes, one on each side of the brain located at about the level of the ears. These lobes allow a person to tell one smell from OCCIPITAL LOBE another and one sound from another. They also ◦ Located at the back of the brain, behind help in sorting new information and are believed to the parietal lobe and temporal lobe. be responsible for short-term memory. ◦ Concerned with many aspects of vision. Right Lobe - Mainly involved in visual memory (i.e., memory for pictures and faces). Not only is the occipital lobe mainly responsible for visual reception, it also Left Lobe - Mainly involved in verbal memory (i.e., contains association areas that help in the memory for words and names). visual recognition of shapes and colors. Damage to this lobe can cause visual deficits DR. ELI DEHOPE Emotions DR. ELI DEHOPE Memory DR. ELI DEHOPE Brain Development is Amazing! The development of synapses occurs at an amazing rate during a child’s early years, in direct response to the young child's experiences. Some of these synapses are strengthened and remain intact, but many are gradually discarded. This process of synapse elimination—or pruning—is a normal part of development Myelin is the white fatty tissue that insulates mature brain cells by forming a sheath, thus ensuring clear transmission across synapses. Children process information slower because they lack the needed Myelin. Brain development continues throughout the lifespan. This allows humans to continue to learn, remember, and adapt to new circumstances What About Trauma and the Brain???? The Amygdala is a small almond-shaped structure located deep in the middle of the temporal lobe. The amygdala is designed to: ◦ detect threats in the environment and activate the “fight or flight” response. ◦ activate the sympathetic nervous system to help you deal with the threat. ◦ helps you store new emotional or threat-related memories. The Prefrontal Cortex regulates attention and awareness and is designed to: ◦ make decisions about the best response to a situation. ◦ Initiate conscious, voluntary behavior. ◦ Determine the meaning and emotional significance of events. ◦ Regulate emotions. ◦ Inhibit or correct dysfunctional reactions. Studies of response to threat in people with PTSD show: ◦ a hyper reactive amygdala. ◦ a less activated medial PFC. In other words, the amygdala reacts too strongly to a potential threat while the medial PFC is impaired in its ability to regulate the threat response. The Brain Changes over a Person’s Lifetime Brain Development and External Events Attachment Human brains function best when they are adequately stimulated but simultaneously protected from overwhelming stress. For people, Trauma this explains a need for order, safety and protection. Poverty and hunger Homelessness Synapses, Myelins and Plasticity DR. ELI DEHOPE Perception and Appraisal Going to a Party ◦ A person age 60 ◦ A person age 20 Safety ◦ A child who lives with his mother in a car ◦ A child who lives with his mother in an apartment in the city ◦ A child who lives with his mother in a house in the suburbs Stopped by a police officer ◦ A person who is white ◦ A person who is black What is trauma? Let’s talk physical trauma first… Physical Injuries directly to the Brain ◦ Traumatic Brain Injury ◦ Falls, Sports, Assaults, Shaken Baby Syndrome, Domestic Violence, Motor Vehicle, Blasts ◦ Anoxia – deprivation of oxygen ◦ Penetration into the skull (gun shot…) DR. ELI DEHOPE SLEEPY CABBY DR. ELI DEHOPE MILITARY DR. ELI DEHOPE SPORTS DR. ELI DEHOPE SOME BASICS THAT GET IMPACTED COGNITIVE FUNCTIONS Speed of Processing and Integration of Attention Thoughts Perseveration Confusion Concentration Executive Functions ◦ Judgment ◦ Problem solving Language Processing ◦ Decision making ◦ Inhibition Memory DR. ELI DEHOPE Drugs also affect Neurology We know that drug use and addiction is a disease that affects both brain and behavior DR. ELI DEHOPE DR. ELI DEHOPE The Brain: Basic Drives and Motivators Instinct - An instinct is an innate biological force, which commands the organism to behave in a particular way. Motivation - external inputs and drives affected behavior of organisms, in addition to the internal drives. Hunger – the desire to sustain oneself Nurturing – need to reproduce and continue the species Avoiding Pain - The behavioral consequences and responses to pain are acquired during life. Emotional Responses – Emotions drive behavior – difference between automatic vs. conscious emotions DR. ELI DEHOPE Mental Health and the Brain Thought Disorders DR. ELI DEHOPE Mental Health and the Brain – Emotional Issues DR. ELI DEHOPE Mental Health and the Brain- Behavioral These positron emission tomography (PET) scans show that patients with ADHD had lower levels of dopamine transporters in the nucleus accumbens DR. ELI DEHOPE BEHAVIOR AS RESULT OF TRAUMA Depends on age and prior The brain is physically changed experiences ◦ Some areas of the brain are hyper- charged while others are more Depends on how aware passive someone is ◦ Stress responses also change – Depends on past coping skills ability to negotiate the “new normal” But it really depends on how functional the brain is especially Emotional responses and in the prefrontal and frontal dysregulation lobes Numbing COMMON BEHAVIORAL ISSUES AFTER TRAUMA •Impulsiveness Irrationality and Illogic •Anger and aggressiveness Poor concentration •Lethargy and passiveness Emotional instability mood swings •Poor memory depression suicide ideation •Inappropriate social skills •Frustration Poor self-awareness Disinhibition and hyper-sexuality DR. ELI DEHOPE Self Awareness Developed throughout the Brain consciousness as opposed to unconsciousness knowledge of the world around us sense of self through continuity of experience using personal history to understand the present and future.

Only primates have temporal lobes, which are largest in man, accommodating 17% of the cerebral cortex and including areas with auditory, olfactory, vestibular, visual and linguistic functions. The hippocampal formation, on the medial side of the lobe, includes the parahippocampal gyrus, subiculum, hippocampus, dentate gyrus, and associated white matter, notably the fimbria, whose fibres continue into the fornix. The hippocampus is an inrolled gyrus that bulges into the temporal horn of the lateral ventricle. Association fibres connect all parts of the cerebral cortex with the parahippocampal gyrus and subiculum, which in turn project to the dentate gyrus. The largest efferent projection of the subiculum and hippocampus is through the fornix to the hypothalamus. The choroid fissure, alongside the fimbria, separates the temporal lobe from the optic tract, hypothalamus and midbrain. The amygdala comprises several nuclei on the medial aspect of the temporal lobe, mostly anterior the hippocampus and indenting the tip of the temporal horn. The amygdala receives input from the olfactory bulb and from association cortex for other modalities of sensation.

  • The Brain Is Contained Within the Cranium, and Constitutes the Upper, Greatly Expanded Part of the Central Nervous System
    The brain is contained within the cranium, and constitutes the upper, greatly expanded part of the central nervous system. Henry Gray (1918) Looking through the gray outer layer of the cortex, you can see a mass of white matter. At the center is a cluster of large nuclei, including the basal ganglia, the hippocampi, the amygdalae, and two egg-shaped structures at the very center, barely visible in this figure, the thalami. The thalami rest on the lower brainstem (dark and light blue). You can also see the pituitary gland in front (beige), and the cerebellum at the rear of the brain (pink). In this chapter we will take these structures apart and re-build them from the bottom up. 09_P375070_Ch05.indd 126 1/29/2010 4:08:25 AM CHAPTER 5 The brain OUTLINE 1.0 Introduction 127 3.2 Output and input: the front-back division 143 1.1 The nervous system 128 3.3 The major lobes: visible and hidden 145 1.2 The geography of the brain 129 3.4 The massive interconnectivity of the cortex and thalamus 149 2.0 Growing a brain from the bottom up 133 3.5 The satellites of the subcortex 151 2.1 Evolution and personal history are expressed in the brain 133 4.0 Summary 153 2.2 Building a brain from bottom to top 134 5.0 Chapter review 153 3.0 From ‘ where ’ to ‘ what ’ : the functional 5.1 Study questions 153 roles of brain regions 136 5.2 Drawing exercises 153 3.1 The cerebral hemispheres: the left-right division 136 1.0 INTRODUCTION found.

    FUNCTION OF CEREBRAL CORTEX Course: Neuropsychology CC-6 (M.A PSYCHOLOGY SEM II); Unit I By Dr. Priyanka Kumari Assistant Professor Institute of Psychological Research and Service Patna University Contact No.7654991023; E-mail- [email protected] The cerebral cortex—the thin outer covering of the brain-is the part of the brain responsible for our ability to reason, plan, remember, and imagine. Cerebral Cortex accounts for our impressive capacity to process and transform information. The cerebral cortex is only about one-eighth of an inch thick, but it contains billions of neurons, each connected to thousands of others. The predominance of cell bodies gives the cortex a brownish gray colour. Because of its appearance, the cortex is often referred to as gray matter. Beneath the cortex are myelin-sheathed axons connecting the neurons of the cortex with those of other parts of the brain. The large concentrations of myelin make this tissue look whitish and opaque, and hence it is often referred to as white matter. The cortex is divided into two nearly symmetrical halves, the cerebral hemispheres . Thus, many of the structures of the cerebral cortex appear in both the left and right cerebral hemispheres. The two hemispheres appear to be somewhat specialized in the functions they perform. The cerebral hemispheres are folded into many ridges and grooves, which greatly increase their surface area. Each hemisphere is usually described, on the basis of the largest of these grooves or fissures, as being divided into four distinct regions or lobes. The four lobes are: • Frontal, • Parietal, • Occipital, and • Temporal.
