Serotonin effects on frequency tuning of inferior colliculus neurons.
We investigated the modulatory effects of serotonin on the tuning of 114 neurons in the central nucleus of the inferior colliculus (ICc) of Mexican free-tailed bats and how serotonin-induced changes in tuning influenced responses to complex signals. We obtained a "response area" for each neuron, defined as the frequency range that evoked discharges and the spike counts evoked by those frequenci...
متن کاملTracking an invisible target reveals spatial tuning of neurons in the rostral superior colliculus is not dependent on visual stimuli.
Editor's Note: These short, critical reviews of recent papers in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to summarize the important findings of the paper and provide additional insight and commentary. For more information on the format and purpose of the Journal Club, please see Review of Hafed et al. The superior colliculus (SC) plays an esse...
متن کاملContribution of the primate superior colliculus to inhibition of return.
The phenomenon of inhibition of return (IOR) has generated considerable interest in cognitive neuroscience because of its putative functional role in visual search, that of placing inhibitory tags on objects that have been recently inspected so as to direct further search to novel items. Many behavioral parameters of this phenomenon have been clearly delineated, and based on indirect but conver...
متن کاملRecruitment of a head-turning synergy by low-frequency activity in the primate superior colliculus.
Low-frequency activity within the oculomotor system helps bridge sensation and action. Given ocular stability, low-frequency activity sustained by some neurons within the intermediate and deep superior colliculus (dSC) is assumed to be separated from motor output. However, the dSC is an orienting structure and the influence of low-frequency dSC activity at other effectors remains untested. We s...
متن کاملNeurons in the primate superior colliculus coding for arm movements in gaze-related coordinates.
In the intermediate and deep layers of the superior colliculus (SC), a well-established oculomotor structure, a substantial population of cells is involved in the control of arm movements. To examine the reference frame of these neurons, we recorded in two rhesus monkeys (Macaca mulatta) the discharges of 331 neurons in the SC and the underlying mesencephalic reticular formation (MRF) while mon...
