The lunate sulcus marks the transition between V1 and V2, the primary and secondary visual cortices. [3] The lunate sulcus lies further back in the human brain than in the chimpanzee's. [4] The evolutionary expansion in humans of the areas in front of the lunate sulcus would have caused a shift in the location of the fissure.
Magnetoencephalography – a technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers In research, MEG's primary use is the measurement of time courses of activity. MEG can resolve events with a precision of 10 milliseconds or faster ...
The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. [2] A sulcus is a shallow groove that surrounds a gyrus or part of a gyrus. A fissure is a deeper furrow that divides the brain into lobes, and also into the two hemispheres as the longitudinal fissure. [4]
A brain atlas is composed of serial sections along different anatomical planes of the healthy or diseased developing or adult animal or human brain where each relevant brain structure is assigned a number of coordinates to define its outline or volume.
Unlike the topographic maps of the senses, the neurons of the motor cortex are efferent neurons that exit the brain instead of bringing information to the brain through afferent connections. The motor system is responsible for initiating voluntary or planned movements ( reflexes are mediated at the spinal cord level, so movements associated ...
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. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Why brain rot and bed rotting are a response to burnout — and what mental health experts say about it. ... “These trends are a response to a world that’s made us feel like we must be ...
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
