The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
This development section covers changes in brain structure over time. 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.
The term limbic system was introduced in 1952 by Paul MacLean [15] to describe the set of structures that line the deep edge of the cortex (Latin limbus meaning border): These include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean later suggested that the limbic structures comprise the neural basis of emotion.
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
Magnetic resonance imaging has been used extensively to investigate brain structure and function non-invasively in healthy human subjects. An important example is diffusion tensor imaging, which relies on the restricted diffusion of water in tissue in order to produce axon images. In particular, water moves more quickly along the direction ...
Some aspects of brain structure are common to almost the entire range of animal species; [6] others distinguish "advanced" brains from more primitive ones, or distinguish vertebrates from invertebrates. [4] The simplest way to gain information about brain anatomy is by visual inspection, but many more sophisticated techniques have been developed.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
Speech production becomes more difficult when sentences are complex; for example, the passive voice is a grammatically complex structure that is harder for those with Broca's aphasia to comprehend. Wernicke's area is crucial for language development, focusing on the comprehension of speech, rather than speech production.
