Here, c-fos labeling shows the 2 kHz tonotopic band as well as an increase in c-fos-labelled cells over a broad range of the inferior colliculus. Compare this background activity with Figure 6(a) that had no enhanced neonatal exposure.
Each animal was anaesthetized through the administration of a mixture of tiletamine/zolazepam (1: 1; Zoletil 100[R]; 50 mg/kg i.p.; VIRBAC Srl, Milan, Italy) and subsequently inserted into a stereotaxic apparatus in order to carry out an accurate craniotomy which, through small holes in the skull, allowed the surgical implantation of two intracranial electrodes in the dura mater, immediately over the cortex, for the electrocorticographic recordings and one electrode in the inferior colliculus for stimulation.
This insignificant alteration in V ipsilateral amplitude may be explained by the fact that the V wave corresponds to the analysis of information at the level of inferior colliculus. The processing of auditory information is bilateral but is predominantly contralateral starting from the II wave onward.
For instance, within the superior colliculus (SC) -- a midbrain area that initiates eye movements to peripheral stimuli directly based on input from the eyes -, much more neural tissue is dedicated to processing foveal signals than to processing peripheral signals.
Neck muscle responses to stimulation of monkey superior colliculus. I.
In normal anatomy, the verumontanum or seminal colliculus is a protrusion found on the posterior wall of the prostatic urethra.
In addition, lesions of the parietal lobe and superior temporal lobe in humans have been associated with difficulties in several processes related to orienting (Losier & Klein, 2001), and these areas, along with the pulvinar, superior colliculus and frontal eye fields, form part of the orienting network.
The distance from the most anterior point of the anterior colliculus to the center of the intercollicular groove was 11.68+-1.13 mm.
Wave V is believed to originate from the inferior colliculus (19-20).
In addition, the rostral superior colliculus projects to the Edinger-Westphal nucleus via the primary, shorter route through the pretectum and also through a secondary, longer route through the nucleus reticularis tegmenti pontis (pons), cerebellar cortex, and cerebellar nuclei.
The 20th chapter discusses the role of the superior colliculus and the mutual influence between cortical and subcortical structures in eye movements and sensory-motor integration.
In previous studies [31, 32], retinal ganglion cells were labeled by injection of 3% fluorogold into both sides of superior colliculus and the numbers and distribution of RGC were observed.
