  2. Trisynaptic circuit - Wikipedia

    en.wikipedia.org/wiki/Trisynaptic_circuit

    The amygdala is an almond-shaped group of nuclei found deep and medially within the temporal lobes of the brain. Known to be the area of the brain responsible for emotional reaction, but plays an important role in processing of memory and decision making as well. It is part of the limbic system.

  3. Prefrontal cortex - Wikipedia

    en.wikipedia.org/wiki/Prefrontal_cortex

    The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...

  4. Frontostriatal circuit - Wikipedia

    en.wikipedia.org/wiki/Frontostriatal_circuit

    The role of frontostriatal circuits is not well understood. Two of the common theories are action selection and reinforcement learning. The action selection hypothesis suggest that frontalcortex generates possible actions and the striatum selects one of these actions by inhibiting the execution of other actions while allowing the selected action execution.

  5. Orbitofrontal cortex - Wikipedia

    en.wikipedia.org/wiki/Orbitofrontal_cortex

    The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making.In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.

  6. Dorsomedial prefrontal cortex - Wikipedia

    en.wikipedia.org/wiki/Dorsomedial_prefrontal_cortex

    The dorsomedial prefrontal cortex (dmPFC [1] [2] or DMPFC [3] [4] is a section of the prefrontal cortex in some species' brain anatomy.It includes portions of Brodmann areas BA8, BA9, BA10, BA24 and BA32, [5] although some authors identify it specifically with BA8 and BA9.

  7. Ventromedial prefrontal cortex - Wikipedia

    en.wikipedia.org/wiki/Ventromedial_prefrontal_cortex

    The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. [2]

  8. Hippocampal subfields - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_subfields

    CA3 has been implicated in a number of working theories on memory and hippocampal learning processes. Slow oscillatory rhythms (theta-band; 3–8 Hz) are cholinergically driven patterns that depend on coupling of interneurons and pyramidal cell axons via gap junctions, as well as glutaminergic (excitatory) and GABAergic (inhibitory) synapses.

  9. Dorsolateral prefrontal cortex - Wikipedia

    en.wikipedia.org/wiki/Dorsolateral_prefrontal_cortex

    The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [1] The DLPFC is not an anatomical structure, but rather a functional one.
