  2. Posterior cingulate cortex - Wikipedia

    en.wikipedia.org/wiki/Posterior_cingulate_cortex

    Posterior cingulate cortex. Medial surface. (Areas 23 and 31 at center right.) The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the "limbic lobe". The cingulate cortex is made up of an area around the midline of the brain.

  3. Default mode network - Wikipedia

    en.wikipedia.org/wiki/Default_mode_network

    Posterior cingulate cortex (PCC) & precuneus: Combines bottom-up (not controlled) attention with information from memory and perception. The ventral (lower) part of PCC activates in all tasks which involve the DMN including those related to the self, related to others, remembering the past, thinking about the future, and processing concepts ...

  4. Memory B cell - Wikipedia

    en.wikipedia.org/wiki/Memory_B_cell

    In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centers of the secondary lymphoid organs. Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. [1] Their function is to memorize the characteristics of the antigen ...

  5. Dentate gyrus - Wikipedia

    en.wikipedia.org/wiki/Dentate_gyrus

    The dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum.The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, [1] [2] the spontaneous exploration of novel environments [2] and other functions.

  6. Cerebral cortex - Wikipedia

    en.wikipedia.org/wiki/Cerebral_cortex

    The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [8] and makes up 40% of the brain's mass. [2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% is made up of the ...

  7. Trisynaptic circuit - Wikipedia

    en.wikipedia.org/wiki/Trisynaptic_circuit

    The cingulate cortex is separated into an anterior and a posterior region, which corresponds to areas 24, 32, 33 (anterior) and 23 (posterior) of the Brodmann areas. The anterior region receives information mainly from the mamillary bodies while the posterior cingulate receives information from the subiculum via the Papez circuit.

  8. Posterior parietal cortex - Wikipedia

    en.wikipedia.org/wiki/Posterior_parietal_cortex

    The posterior parietal cortex (the portion of parietal neocortex posterior to the primary somatosensory cortex) plays an important role in planned movements, spatial reasoning, and attention. Damage to the posterior parietal cortex can produce a variety of sensorimotor deficits, including deficits in the perception and memory of spatial ...

  9. Basal ganglia - Wikipedia

    en.wikipedia.org/wiki/Basal_ganglia

    The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates, differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum. Positioned at the base of the forebrain and the top of the ...
