Trisynaptic loop
WebAn example of a neural circuit is the trisynaptic circuit in the hippocampus. Another is the Papez circuit linking the hypothalamus to the limbic lobe. There are several neural circuits in the cortico-basal ganglia-thalamo-cortical loop. These circuits carry information between the cortex, basal ganglia, thalamus, and back to the cortex. WebNAME FUNCTION Cerebral cortex responsible for the higher-level processes of the human brain, including language, memory, reasoning, thought, learning, decision-making, emotion, intelligence and personality Corpus callosum ensures both sides of the brain can communicate and send signals to each other. Limbic System involved in our behavioural …

The trisynaptic circuit, or trisynaptic loop is a relay of synaptic transmission in the hippocampus. The circuit was initially described by the neuroanatomist Santiago Ramon y Cajal, in the early twentieth century, using the Golgi staining method. After the discovery of the trisynaptic circuit, a series of research has … See more Entorhinal cortex 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 includes layers I … See more There are many brain structures that transmit information to, and from the trisynaptic circuit. The activity of these different structures can be directly or indirectly modulated … See more Role in rhythm generation It has been proposed that the trisynaptic circuit is responsible for the generation of hippocampal theta waves. These waves are responsible for the synchronization of different brain regions, especially the limbic system. In … See more WebThe trisynaptic loop, as the main circuit of the hippocampus responsible for information transfer between the hippocampus and the cortex, is also the circuit producing SWRs.This circuit provides the pathway by which SWRs affect the cortical areas, and also receive inputs from them. Consequently, this loop is shown to be the pathway responsible for conversion …
WebMay 28, 2014 · The hippocampal CA1 field processes spatial information, but the relative importance of intra- vs. extra-hippocampal sources of input into CA1 for spatial behavior is unclear. To characterize the relative roles of these two sources of input, originating in the hippocampal field CA3 and in the medial entorhinal cortex (MEC), we studied effects of … WebStudies in the 1970s placed an emphasis on the so-called trisynaptic loop pathway. Each synapse in the loop is excitatory and information flow is unidirectional. The hippocampus receives sensory information from uni- and polymodal cortices via the entorhinal cortex (EC).
