Thalamus

The thalamus (from Greek θάλαμος, "chamber") is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain. Some of its functions are the relaying of sensory and motor signals to the cerebral cortex, and the regulation of consciousness, sleep, and alertness. The two parts of the thalamus surround the third ventricle. It is the main product of the embryonic diencephalon.

Anatomy

The thalamus is located in the forebrain superior to the midbrain, near the center of the brain, with nerve fibers projecting out to the cerebral cortex in all directions. The medial surface of the thalamus constitutes the upper part of the lateral wall of the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic adhesion.

Morphology

The two halves of the thalamus are prominent bulb-shaped masses, about 5.7 cm in length, located obliquely (about 30°) and symmetrically on each side of the third ventricle. Both parts of the thalamus, in the human, are about the size and shape of a walnut. These are about three centimetres in length, at the widest part 2.5 centimetres across and about 2 centimetres in height (comparable to an unshelled walnut, with the nut-shell joining in the horizontal plane).

Thalamus Ltd

Thalamus Ltd (also known as Thalamus) was a British computer game developer that published titles for a number of 8-bit and 16-bit platforms during the late 1980s and early 1990s.

History

Genesis

Thalamus Ltd was created in 1986 as an in-house software publishing label of British magazine publisher Newsfield Publications Ltd, to take advantage of their leading position publishing computer game magazines, such as Crash and Zzap!64, during the mid-1980s. Ex-Activision PR Manager Andrew Wright was assigned the position of Company Director and Newsfield staff writer Gary Liddon was appointed Technical Executive. The company was initially based in Canonbury, North London, in an office shared with staff of Newsfield's newly launched lifestyle magazine LM.

First Titles

Thalamus capitalised on the success of the Commodore 64 gaming scene by releasing their first batch of titles on this platform. Having established numerous contacts within the C64 development scene through the popularity of their Zzap!64 gaming magazine, Thalamus were able to sign up Finnish programmer Stavros Fasoulas to develop their first three titles, Sanxion, Delta and Quedex. Sanxion was the first release to bear the Thalamus name, and it garnered a Sizzler rating from Zzap!64 - this led to accusations of favouritism from rival publications, in particular Commodore User, despite the game deserving the award - it was technically competent, visually attractive, and ran at breakneck speed for its time. Legendary C64 musician Rob Hubbard came on board to provide the music for the first two titles, while Matt Gray provided the music for Quedex. "Thalamusik", the loading tune that accompanied the C64 version of Sanxion proved to be so popular amongst fans that Zzap!64 later included a full synthesised version of Rob Hubbard's classic tune on one of their cover cassettes.
