(1) Neurons in the upper layers of the superior colliculus have well - defined receptive fields.

(2) These include the superior colliculus, which is crucial in eye movements and may have other sensory functions; and, probably, circuits running through the amygdala, which registers emotion.

(3) Objective To study the tissue culture technique for superior colliculus explanted from newborn rats and to observe the growth status dynamically.

(4) Damage to a visual area in the brainstem, the superior colliculus, had the reverse effect.

(5) Also some changes were found in vestibulum, inferior olivary nucleus, vagus nerve nucleus, superior colliculus, basal ganglion, pons, Cerebellumand motor area of cortex.

(6) The central subcortical structure involved in the generation of visually guided saccadic eye movements is the superior colliculus.

(7) Although the ontogeny of the optic system to the lateral geniculate body, superior colliculus have been well studied.

(8) The tegmentum —— tectum —— tegmentum connections are only concerned with the mid - dle and deep layers of the superior colliculus.

(9) "When images begin to fade, the uncertainty about where to look increases the fluctuations in superior colliculus activity, triggering a microsaccade," adds Krauzlis.
