The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
Subfornical organ of a mouse. In this photomicrograph, the subfornical organ (arrow) is located on the undersurface of the fornix in the upper part of the third ventricle. The cells in this coronal section of the brain were colored with a bluish dye ("Nissl stain"). The thalamus is at the bottom of the photo. The bar at the lower right ...
The fusiform gyrus is the hypothetical location of V4α, a secondary area for colour processing. More: Colour centre. Visual area V4 is one of the visual areas in the extrastriate visual cortex. In macaques, it is located anterior to V2 and posterior to the posterior inferotemporal area (PIT). It comprises at least four regions (left and right ...
The human 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 ...
Schematic diagram of the human eye. It shows a horizontal section through the right eye. The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the eye and support the deeper structures.
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.
Scientists just discovered a secret fourth membrane in the human brain. Here's why that matters.
The experiment had subjects view images of different objects, including faces (as a control group), body parts, animals, parts of the face and intimate objects. While viewing the images, the subjects were scanned with an fMRI to see what area of the brain was activated. Through the trials a compilation of the fMRI’s was made.
