What part of the brain actually receives the image?
Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the brain.
Where does the brain receive visual information?
The primary visual cortical receiving area is in the occipital lobe. The primary visual cortex is characterized by a unique layered appearance in Nissl stained tissue. Nearly the entire caudal half of the cerebral cortex is dedicated to processing visual information.
Where is the visual cortex located?
occipital lobe
The primary visual cortex is found in the occipital lobe in both cerebral hemispheres. It surrounds and extends into a deep sulcus called the calcarine sulcus.
Where is the visual pathway?
The Visual Pathway. The visual pathway consists of the retina, optic nerves, optic chiasm, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex. The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon.
How the brain processes information?
Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals. The sensory information is repeatedly transformed by the algorithms of the brain in both bottom-up and top-down processing.
What does the brain do as it receives the information?
The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells which stabilize the tissue.
Where is information stored in the brain?
Different types are stored across different, interconnected brain regions. For explicit memories – which are about events that happened to you (episodic), as well as general facts and information (semantic) – there are three important areas of the brain: the hippocampus, the neocortex and the amygdala.
