The entorhinal cortex (EC) is a structure in the brain located in the medial temporal lobe.The EC is composed of six distinct layers. The superficial (outer) layers, which include layers I through III, are mainly input layers that receive signals from other parts of the EC, but also project to hippocampal structures via the perforant path.
This is the oldest brain in the Triune Theory and anatomically is made up of the brain stem and the cerebellum. [10] In reptiles, both the brain stem and cerebellum dominate and are the control centres for basic function. It has been found that these two parts of the brain are responsible for emotions such as paranoia, obsession and compulsion. [5]
The prefrontal cortex, with its agenda of integration, is the part of the brain that can get the other parts to work together for the good of the individual. Hoffmann claims that in many humans the reptilian cortex (agenda: territory and reproduction; in humans that translates to power and sex) is out of control, and the amygdala stokes the ...
The brain is made up of individual cells (neurons) that contain specialized features such as dendrites, a cell body, and an axon. Neurons are cells differentiable from other tissues in the body. Neurons differ in size, shape, and structure according to their location or functional specialization.
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
In adult humans the volume of the hippocampus on each side of the brain is about 3.0 to 3.5 cm 3 as compared to 320 to 420 cm 3 for the volume of the neocortex. [ 160 ] There is also a general relationship between the size of the hippocampus and spatial memory.
