  2. Trisynaptic circuit - Wikipedia

    en.wikipedia.org/wiki/Trisynaptic_circuit

    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.

    en.wikipedia.org/wiki/Brodmann_area_38

    Brodmann area 38, also BA38 or temporopolar area 38 (H), is part of the temporal cortex in the human brain. BA 38 is at the anterior end of the temporal lobe, known as the temporal pole. BA38 is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex.

    en.wikipedia.org/wiki/Orbital_part_of_inferior...

    The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. [1]In humans, this region is bordered by the triangular part of the inferior frontal gyrus (pars triangularis) and, surrounding the anterior horizontal limb of the lateral sulcus, a portion of the opercular part of inferior frontal gyrus (pars opercularis).

    It is bounded caudally by the angular area 39 (H), rostrally and dorsally by the caudal postcentral area 2, and ventrally by the subcentral area 43 and the superior temporal area 22 (Brodmann-1909). Cytoarchitectonically defined subregions of rostral BA40/the supramarginal gyrus are PF, PFcm, PFm, PFop, and PFt. Area PF is the homologue to ...

    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).

    [1] [2] Specifically, BA47 is active in tasks regarding semantics, or identifying the meaning of words and sentences. [ 3 ] [ 4 ] [ 5 ] To understand language semantics, consider Dapretto and Bookheimer’s (1999) study where participants needed to identify that there was a difference between the sentences, “The man was attacked by the ...

    en.wikipedia.org/wiki/Tripartite_synapse

    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 ...
