A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...
Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception.

Because this migration does not occur, the skull, and all involved muscles, are never formed. [2] Without the presence of the neurocranium , the brain fails to separate into two separate lobes. The hindbrain proceeds to develop normally, allowing for the child to be carried to term, but the diencephalon and ocular lobe remain small and ...
57,541 copies of the FreeSurfer software package have been registered for use as of April 2022 [5] and it is a core tool in the processing pipelines of the Human Connectome Project, [6] the UK Biobank, [7] the Adolescent Brain Cognitive Development Study, [8] and the Alzheimer's Disease Neuroimaging Initiative.
Connectomics is the production and study of connectomes: comprehensive maps of connections within an organism's nervous system.More generally, it can be thought of as the study of neuronal wiring diagrams with a focus on how structural connectivity, individual synapses, cellular morphology, and cellular ultrastructure contribute to the make up of a network.
Despite the reduced brain matter, the man lived a relatively normal life; he was a married civil servant with two kids. He also scored an IQ of 75 which is considered low but not disabled.
P300 latency and amplitude trajectories across the lifespan as obtained from the cross-sectional dataset. Dots represent scores from individual participants. From From P300 Development across the Lifespan: A Systematic Review and Meta-Analysis. [1] The latency and amplitude of the P300 response may vary as a function of age.
The folded cortex creates a larger surface area for the brain in humans and other larger mammals, without the need of increasing the size of the skull. [1] In the human brain , two-thirds of the folded cortex is buried within the sulci, if the division of the hemispheres by the longitudinal fissure is taken into account.
