For more information, please contact [email protected]. ii Abstract Probing the functions of human hippocampal subfields is a promising area of research in cognitive neuroscience. However, defining subfield borders in Magnetic Resonance Imaging (MRI) is challenging. Here, we present a user-guided, semi-automated protocol for segmenting hippocampal subfields on T2-weighted images obtained with 7-Tesla MRI. The protocol takes advantage of extant knowledge about regularities in hippocampal morphology and ontogeny that have not been systematically considered in prior related work. An image feature known as the hippocampal ‘dark band’ facilitates tracking of subfield continuities, allowing for unfolding and segmentation of convoluted hippocampal tissue.

  • Age Differentiation Within Grey Matter, White Matter and Between Memory and White Matter in an Adult Lifespan Cohort

Waldorp1, Cam-CAN3, & Rogier A. Kievit2 *corresponding author: [email protected], 1Department of Psychology, University of Amsterdam, Roetersstraat 15, 1018 WB Amsterdam, The Netherlands, 2MRC Cognition and Brain Sciences Unit, 15 Chaucer Road, Cambridge CB2 7EF, UK, 3Cambridge Centre for Ageing and Neuroscience (Cam-CAN), University of Cambridge and MRC Cognition and Brain Sciences Unit, Cambridge, UK Abstract It is well-established that brain structures and cognitive functions change across the lifespan. A longstanding hypothesis called age differentiation additionally posits that the relations between cognitive functions also change with age. To date however, evidence for age-related differentiation is mixed, and no study has examined differentiation of the relationship between brain and cognition. Here we use multi-group Structural Equation Modeling and SEM Trees to study differences within and between brain and cognition across the adult lifespan (18-88 years) in a large (N>646, closely matched across sexes), population-derived sample of healthy human adults from the Cambridge Centre for Ageing and Neuroscience (www.cam- can.org). After factor analyses of grey-matter volume (from T1- and T2-weighted MRI) and white-matter organisation (fractional anisotropy from Diffusion-weighted MRI), we found evidence for differentiation of grey and white matter, such that the covariance between brain factors decreased with age.

  • Brain Anatomy
    BRAIN ANATOMY Adapted from Human Anatomy & Physiology by Marieb and Hoehn (9th ed.) The anatomy of the brain is often discussed in terms of either the embryonic scheme or the medical scheme. The embryonic scheme focuses on developmental pathways and names regions based on embryonic origins. The medical scheme focuses on the layout of the adult brain and names regions based on location and functionality. For this laboratory, we will consider the brain in terms of the medical scheme (Figure 1): Figure 1: General anatomy of the human brain Marieb & Hoehn (Human Anatomy and Physiology, 9th ed.) – Figure 12.2 CEREBRUM: Divided into two hemispheres, the cerebrum is the largest region of the human brain – the two hemispheres together account for ~ 85% of total brain mass. The cerebrum forms the superior part of the brain, covering and obscuring the diencephalon and brain stem similar to the way a mushroom cap covers the top of its stalk. Elevated ridges of tissue, called gyri (singular: gyrus), separated by shallow groves called sulci (singular: sulcus) mark nearly the entire surface of the cerebral hemispheres. Deeper groves, called fissures, separate large regions of the brain. Much of the cerebrum is involved in the processing of somatic sensory and motor information as well as all conscious thoughts and intellectual functions. The outer cortex of the cerebrum is composed of gray matter – billions of neuron cell bodies and unmyelinated axons arranged in six discrete layers. Although only 2 – 4 mm thick, this region accounts for ~ 40% of total brain mass. The inner region is composed of white matter – tracts of myelinated axons.

  • Grey Matter Matters: Teaching Strategies for the Brain Compatible
    Teaching & Professional Practice Grey matter matters Teaching strategies for the brain compatible classroom Andrea Thompson Primary teacher, Avondale Schools, Cooranbong, NSW The brain is extremely complex.

When we remember that “God’s intelligence its neural networks, depending on increased or is the basis of human intelligence” (Sire, 1977, p. 35), decreased use, making it malleable or ‘plastic’. the complexity of the brain is not surprising. This plasticity allows for incredible changes to take place, which were once thought impossible. The brain’s ability to rewire This article explores current research in this Our brain has been designed by a loving God, with area and offers brain compatible strategies the ability to change its own wiring to make it more that teachers can employ in the classroom to efficient. Neuroplasticity is the word that describes make learning more efficient, to raise student the brain’s ability to rewire and can be defined as achievement, and to facilitate a healthy learning the “genetically driven overproduction of synapses environment. and the environmentally driven maintenance and pruning of synaptic connections” (Cicchetti and Christians have long agreed with the Psalmist Curtis, 2006, as cited by Willis and Kappan, 2008, that humans are “so wonderfully complex” (Psalm p. 4). The brain’s plasticity allows it to reshape and Our brain is 139:4 NLT), yet it is only comparatively recently reorganise networks, depending on increased or constantly that advances in neuroscience have allowed decreased use. This makes the brain malleable and learning how researchers to observe how complex the human able to change.
