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 region is conventionally divided into three divisions. CA3a is the part of the cell band that is most distant from the dentate (and closest to CA1). CA3b is the middle part of the band nearest to the fimbria and fornix connection. CA3c is nearest to the dentate, inserting into the hilus.
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 anterior part of the right hippocampus was larger and the posterior part was smaller, compared with sighted individuals. [73] There are several navigational cells in the brain that are either in the hippocampus itself or are strongly connected to it, such as the speed cells present in the medial entorhinal cortex. Together these cells form ...
Broca's area – region of the brain with functions linked to speech production Triangular part of inferior frontal gyrus – part of Broca's area that contributes to propositional (true/false) language comprehension; Caudate nucleus – located within the basal ganglia and involved in learning and memory
View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.
The temporal lobes are a region of the cerebral cortex that is located beneath the Sylvian fissure on both the left and right hemispheres of the brain. [14] Lobes in this cortex are more closely associated with memory and in particular autobiographical memory. [15] The temporal lobes are also concerned with recognition memory.
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
