How the Body Works : The Thalamus The Thalamus The thalamus, shown in red, is part of the forebrain. It plays an integral part in relaying sensory information from the sense organs to the cortex. Acting as a major relay center, the thalamus passes incoming messages on to higher centers in the cortex. A thalamus with its nuclei color coded is represented here. Some nuclei deal with several different types of messages, while other nuclei deal with only one type. The lateral geniculate body relays information to the visual cortex, and the medial geniculate body relays sound information to the auditory cortex. Tags: The Thalamus

Tarsier! PHILIPPINE TARSIERS: All tarsier species are nocturnal in their habits, but like many nocturnal organisms some individuals may show more or less activity during the daytime. Unlike many nocturnal animals, however, tarsiers lack a light-reflecting area (tapetum lucidum) of the eye. They also have a fovea, atypical for nocturnal animals. The tarsier brain is different from other primates in terms of the arrangement of the connections between the two eyes and the lateral geniculate nucleus, which is the main region of the thalamus that receives visual information. The sequence of cellular layers receiving information from the ipsilateral (same side of the head) and contralateral (opposite side of the head) eyes in the lateral geniculate nucleus distinguishes tarsiers from lemurs, lorises, and monkeys, which are all similar in this respect. Some neuroscientists suggested that "this apparent difference distinguishes tarsiers from all other primates, reinforcing the view that they arose in an early, independent line of primate evolution".

How the Body Works : The Visual Mechanism The Visual Mechanism This cross section of a brain, as viewed from above, shows how the image which reaches the retina is coded and relayed to the visual cortex. Light falling on the retina stimulates the fibers of the optic nerve. These fibers join to form a cross, called the optic chiasma, where fibers from the inner side of each eye pass to the visual cortex on the opposite side. Fibers from the outer field of each eye are uncrossed, passing to the visual cortex on the same side. From the optic chiasma, the information passes, via the optic tracts, to the lateral geniculate bodies, where perception of depth occurs, and then onto the optic radiation, which transmits the information to the primary visual cortex, situated in the occipital lobes. The primary visual cortex is responsible for the perception of the position of objects in space, and their relationship to each other, as well as the perception of light and shade. In this way, an overall composite picture of any object is formed. Tags: The Visual Mechanism

How the Body Works : The Auditory Pathways The Auditory Pathways The auditory center, in the brain, shown above in red, is concerned with hearing. Although shown here on the outer surface of the brain, most of this area lies within the temporal lobes and is found within the surface of the cerebral cortex on both sides of the brain. The auditory pathways begin in the nerve fibers of the organ of Corti in the inner ear, where sound waves are converted to nerve impulses. These impulses travel in the auditory nerve to the auditory cortex of the brain. During their passage to the auditory center, some of the auditory nerve fibers cross in the brain stem. This results in the sound which enters one ear passing to both cortices. The impulses are relayed in the lateral lemnisci and from there, via the medial geniculate nuclei, to the auditory cortices in the temporal lobes of the brain, where sound is perceived.

karmienie geniculaty/feeding geniculata Pająk jest bodajże po szóstej wylince (nie dam sobie głowy uciąć, nie licze pająkom wylinek) i ma wilczy apetyt, jak na geniculate przystało:) widać to zresztą po jego reakcji. Karmię go drewnojadami. Tags: acanthoscurria geniculata birdspider spider spinne vogelspinne pajak pająk ptasznik genia
