Archicortex is a type of cortical tissue that consists of three laminae (layers of neuronal cell bodies). Archicortex is most prevalent in the olfactory cortex and the hippocampus, which are responsible for processing smells and forming memories, respectively.

What is the archicortex?
Archicortex is a type of cortical tissue that consists of three laminae (layers of neuronal cell bodies). Archicortex is most prevalent in the olfactory cortex and the hippocampus, which are responsible for processing smells and forming memories, respectively.
What is the archipallium?
The archipallium (pallium is a synonym for cortex) is the hippocampus, which is an internal gyrus, an area of cerebral cortex that has been rolled into the lateral ventricle and is not visible on the surface of the cerebrum.
What is the difference between the neocortex and allocortex?
The allocortex or heterogenetic cortex, and neocortex are the two types of cerebral cortex in the brain. The allocortex is the much smaller area of cortex taking up just 10 %, the neocortex takes up the remaining 90 %.
Is the amygdala part of the allocortex?
The terms VS and VP were introduced in the late 1970s, realizing that in the rat brain, the allocortex (olfactory or piriform cortex and the hippocampus) and the cortical-like basolateral amygdala, like the neocortex, are linked to the basal ganglia via cortical–striatal–pallidal–thalamic circuits (Heimer, 1978).
How many layers are in the Archicortex?
three
In humans, the archicortex makes up the three cortical layers of the hippocampus. It has fewer cortical layers than both the neocortex, which has six, and the paleocortex, which has either four or five….

What is the function of the Paleocortex?
The paleocortex is a structure in the brain. It is primarily associated with an organism’s olfaction, or sense of smell. It is a component of the cerebral cortex, an important part of the central nervous system of all mammals, including human beings.
Which of the following is also known as Rhinencephalon?
In animal anatomy, the rhinencephalon (from the Greek, ῥίς, rhis = “nose”, and ἐγκέφαλος, enkephalos = “brain”), also called the smell-brain or olfactory brain, is a part of the brain involved with smell (i.e. olfaction)….

What structures are near the hippocampus?
The hippocampus is closely associated with the amygdala, hypothalamus, septum, and mammillary bodies such that any stimulation of the nearby parts also marginally stimulates the hippocampus.
Is amygdala part of Papez circuit?
Now, the Amygdala is thought to play a key role in emotion, a structure that was not a part of the Papez circuit until 1952 when MacLean included it in the modified version of the circuit, the limbic system.
