The trisynaptic circuit or trisynaptic loop is a relay of synaptic transmission in the hippocampus.The trisynaptic circuit is a neural circuit in the hippocampus, which is made up of three major cell groups: granule cells in the dentate gyrus, pyramidal neurons in CA3, and pyramidal neurons in CA1.
"Reptilian complex" (also known as the "R-complex", "reptilian brain" or "lizard brain") was the name MacLean gave to the basal ganglia, structures derived from the floor of the forebrain during development. The term derives from the idea that comparative neuroanatomists once believed that the forebrains of reptiles and birds were dominated by ...
Evidence for the role of astrocytes in the integration and processing of synaptic integration presents itself in a number of ways: Astrocytes are excitable cells: In response to stimuli from any of the three components of the tripartite synapse, astrocytes are capable of producing transient changes in their intracellular calcium concentrations through release of calcium stores from the ...
No monopoly of this function by the nervous system, however, can be deduced from this specialisation, not even in its highest state of evolution, as in Man." [4] One of the first ventures on identifying the location of a memory in the brain was undertaken by Karl S. Lashley who removed portions of the brain in rodents.

The PPRF is situated in the pons just [3] ventralmedial to the abducens nucleus. [2] It is located anterior and lateral to the medial longitudinal fasciculus. [citation needed] It is continuous caudally with the nucleus prepositus hypoglossi. [4]

This is likely because the brain enters into a hypodopaminergic state, although there might be a role for noradrenaline also. For these drugs to be reinforcing, they must block more than 50% of the DAT within a relatively short time period (<15 minutes from administration) and clear the brain rapidly to enable fast repeated administration.
