The term limbic system was introduced in 1952 by Paul MacLean to describe the set of structures that line the deep edge of the cortex (Latin limbus meaning border): [18] These include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean later suggested that the limbic structures comprise the neural basis of emotion.
A key physiological function of the CA3 is encoding heteroassociative memories using its recurrent circuitry. A seminal hypothesis by John Lisman postulated that during a single theta cycle, a defined set of CA3 principal neurons can activate each other to form a well defined sequence, and the spikes ( action potentials ) of these cells tend to ...
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
Fimbria-fornix fibers are the hippocampal and subicular gateway to and from subcortical brain regions. [13] [14] 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 ...
An antependium (from Latin ante-and pendēre, "to hang before"; pl.: antependia), also known as a pulpit fall, [1] parament or hanging, or, when speaking specifically of the hanging for the altar, an altar frontal (Latin: pallium altaris), is a decorative piece, usually of textile, but also metalwork, stone or other material, that can adorn a ...
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
The archicortex is most prevalent in the olfactory cortex and the hippocampus, [4] which are responsible for processing smells and forming memories, respectively. [5] Because olfaction is considered to be the phylogenetically oldest sensory modality, [6] and the limbic system, of which the hippocampus is a part, is one of the oldest systems in the brain, [7] it is likely that the archicortex ...
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 ...
