Model of MacLean's Triune Brain hypothesis. The Triune Brain Hypothesis was a once popular, now proven false [1] [2] [3] [4] [5], model of the evolution of the ...
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
Neurobiologists have often had great difficulty distinguishing the VTA in humans and other primate brains from the substantia nigra (SN) and surrounding nuclei. Originally, the ventral tegmental area was designated as a ‘nucleus’, but over time ‘area’ became the more appropriate term used because of the heterogeneous cytoarchitectonic features of the region and the lack of clear ...
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system.It consists of the cerebrum, the brainstem and the cerebellum.
View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.
The visual system and the somatosensory system are active even during resting state fMRI Activation and response in the sensory nervous system. The sensory nervous system is a part of the nervous system responsible for processing sensory information.
Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production.
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.
