  2. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    The principal subdivision of the thalamus into nucleus groups is the trisection of each thalamus (left and right) by a Y-shaped internal medullary lamina. This trisection divides each thalamus into anterior, medial and lateral groups of nuclei. [8] The medial group is subdivided into the medial dorsal nucleus and midline group.

  3. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    The pons lies between the midbrain and the medulla oblongata. It is separated from the midbrain by the superior pontine sulcus, and from the medulla by the inferior pontine sulcus. [9] It contains tracts that carry signals from the cerebrum to the medulla and to the cerebellum and also tracts that carry sensory signals to the thalamus.

  4. Brain - Wikipedia

    This sort of memory is probably stored largely in the cerebral cortex, mediated by changes in connections between cells that represent specific types of information. [117] Instrumental learning is the ability for rewards and punishments to modify behavior. It is implemented by a network of brain areas centered on the basal ganglia. [118]

  5. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    Changes in gene expression alter the levels of proteins in various neural pathways and this has been shown to be evident in synaptic contact dysfunction or loss. This dysfunction has been seen to affect many structures of the brain and has a marked effect on inhibitory neurons resulting in a decreased level of neurotransmission, and subsequent ...

  6. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    This processed information is often relayed to a collection of structures from the telencephalon, diencephalon, and mesencephalon, including the prefrontal cortex, cingulate gyrus, limbic thalamus, hippocampus including the parahippocampal gyrus and subiculum, nucleus accumbens (limbic striatum), anterior hypothalamus, ventral tegmental area ...

  7. Midbrain - Wikipedia

    en.wikipedia.org/wiki/Midbrain

    The midbrain or mesencephalon is the uppermost portion of the brainstem connecting the diencephalon and cerebrum with the pons. [2] It consists of the cerebral peduncles , tegmentum , and tectum . It is functionally associated with vision, hearing, motor control, sleep and wakefulness, arousal ( alertness ), and temperature regulation.

  8. Outline of the human brain - Wikipedia

    en.wikipedia.org/wiki/Outline_of_the_human_brain

    It includes both the normal development of the human brain from infant to adult and genetic and evolutionary changes over many generations. Neural development in humans; Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc. Nonsynaptic plasticity – changes in the axon, dendrites, and soma of individual neurons

  9. Sense of balance - Wikipedia

    en.wikipedia.org/wiki/Sense_of_balance

    The sense of balance or equilibrioception is the perception of balance and spatial orientation. [1] It helps prevent humans and nonhuman animals from falling over when standing or moving. Equilibrioception is the result of a number of sensory systems working together; the eyes ( visual system ), the inner ears ( vestibular system ), and the ...
