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.
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 ...
The self-released mixtape is produced by a variety of producers including Zaytoven and Tarentino. It is hosted by DJ Holiday and comedian Michael Blackson. It was released on August 15, 2013 as a follow-up to his 2011 mixtape, Bang. Bang, Pt. 2 is itself a predecessor to the third mixtape in the Bang series, Bang 3. Although heavily panned upon ...
It is important in mediating saccadic eye movements. [2] It is probably not involved in smooth pursuit. [2] The PPRF generates excitatory bursts that are delivered to the ipsilateral abduecens nucleus to drive ipsilateral saccades (inhibitory saccadic stimuli are meanwhile delivered to the abducens nucleus from the contralateral medulla oblongata).
"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 ...
Central pattern generators (CPGs) are self-organizing biological neural circuits [1] [2] that produce rhythmic outputs in the absence of rhythmic input. [3] [4] [5] They are the source of the tightly-coupled patterns of neural activity that drive rhythmic and stereotyped motor behaviors like walking, swimming, breathing, or chewing.
The retrosplenial cortex (RSC) is a cortical area in the brain comprising Brodmann areas 29 and 30. [1] It is secondary association cortex, making connections with numerous other brain regions. The region's name refers to its anatomical location immediately behind the splenium of the corpus callosum in primates, although in rodents it is ...
Brodmann area 22 is a Brodmann's area that is cytoarchitecturally located in the posterior superior temporal gyrus of the brain. [1] In the left cerebral hemisphere, it is one portion of Wernicke's area. [1] The left hemisphere BA22 helps with generation and understanding of individual words.
