Most famous parts of the brain highlighted in different colours. The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional, connective, and developmental regions are listed in parentheses where appropriate.
The polymorphic layer is often called the hilus or hilar region. [12] The neurons in the polymorphic layer, including mossy cells and GABAergic interneurons, primarily receive inputs from the granule cells in the dentate gyrus in the form of mossy fibers and project to the inner molecular layer of the dentate gyrus via the associational ...
Fimbria-fornix fibers are the hippocampal and subicular gateway to and from subcortical brain regions. [10] [11] Different parts of this system are given different names: White myelinated fibers that cover the ventricular (deep) parts of hippocampus make alveus. Fibers that cover the temporal parts of hippocampus make a fiber bundle that is ...
The cranial region includes the upper part of the head while the; facial region includes the lower half of the head beginning below the ears. The forehead is referred to as the frontal region. The eyes are referred to as the orbital or ocular region. The cheeks are referred to as the buccal region. The ears are referred to as the auricle or ...
In humans, it contains two main interlocking parts: the hippocampus proper (also called Ammon's horn), and the dentate gyrus. [6] [7] In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; [8] short-term memory loss and disorientation are included
According to the British Medical Journal, there are at least three levels of brain function: The brain controls movement and deciphers input from our senses, it manages our cognitive and emotional ...
These methods rely on the haemodynamic response that shows changes in brain activity in relation to changes in blood flow, useful in mapping functions to brain areas. [157] Resting state fMRI looks at the interaction of brain regions whilst the brain is not performing a specific task. [158] This is also used to show the default mode network.
The perirhinal cortex is involved in both visual perception and memory; [1] it facilitates the recognition and identification of environmental stimuli. Lesions to the perirhinal cortex in both monkeys and rats lead to the impairment of visual recognition memory, disrupting stimulus-stimulus associations and object-recognition abilities.
