Abstract

Vibratory stimulus-related responses were recorded from monkey primary somatosensory cortical (SI) neurons while animals performed two tasks. In the movement task, vibratory stimuli served as the go-cue for wris̀t flexion or extension. In the no-movement task, movements normally made in response to vibratory stimuli were extinguished. Area 3a, 3b, and 1 neurons with deep receptive fields (RFs) exhibited greater stimulus-related activity during the movement task than during the no-movement task. Area 3b neurons with cutaneous RFs were similarly enhanced during the movement task, whereas area 1 neurons with cutaneous RFs were less responsive to vibratory stimuli during the movement task. These results suggest that motor-set and/or selective attention may modulate the responsiveness of SI neurons to peripheral stimuli and that changes in sensory responsiveness in SI neurons differ as a function of their cortical location and RF type.

For example, visual saccades involve directed attentional modulation of the responsiveness of visual neurons: responses of neurons with receptive fields in the region of spatial attention (e.g., the target region of the saccade) show transient increases in sensitivity, while neurons with receptive fields in other regions show decreases in sensitivity (Noudoost et al., 2010). Similarly, cortical somatosensory neurons change their responsiveness to mechanosensory stimuli in the transition from passive to active touch mediated by reaching (in primates) or whisking (in rodents) (Hentschke et al., 2006; Nelson et al., 1991). Like saccades and active touch, sniffing can provide an unambiguous and temporally precise behavioral readout of directed attention (Kepecs et al., 2007; Wesson et al., 2008a).
Sensation is an active process involving the sampling and central processing of external stimuli selectively in space and time. Olfaction in particular depends strongly on active sensing due to the fact that—at least in mammals—inhalation of air into the nasal cavity is required for odor detection. This seemingly simple first step in odor sensation profoundly shapes nearly all aspects of olfactory system function, from the distribution of odorant receptors to the functional organization of central processing to the perception of odors. The dependence of olfaction on inhalation also allows for profound modulation of olfactory processing by changes in odor sampling strategies in coordination with attentional state and sensory demands. This review discusses the role of active sensing in shaping olfactory system function at multiple levels and draws parallels with other sensory modalities to highlight the importance of an active sensing perspective in understanding how sensory systems work in the behaving animal.
Cocaine preferentially enhances sensory processing in the upper layers of the primary sensory cortex
2007, Neuroscience

A reduction in response magnitude with repeated sensory stimulation was observed following saline injection in all CSD and MUA response components. This effect, commonly known as sensory adaptation, is thought to be an important sensory coding mechanism to influence the perception of sensory stimuli (Fanselow and Nicolelis, 1999; Moore et al., 1999; Chung et al., 2002; Nicolelis, 2002; Petersen, 2002; Castro-Alamancos, 2004a) and has been detected using a range of sensory modalities in both awake and anesthetized animals (Laskin and Spencer, 1979; Simons, 1985; Nelson et al., 1991; Shu et al., 1993; Wilson, 1998; Ahissar et al., 2001; Chung et al., 2002; Castro-Alamancos, 2004b). We found that the CSD response in layers II/III displayed greater adaptation than that of the thalamocortical inputs to layers IV, V and VI.
Sensory systems are believed to play an important role in drug addiction, particularly in triggering craving and relapse, and it has been shown in previous studies that administration of cocaine can enhance evoked responses in the primary sensory cortex of experimental animals. Primary sensory cortex comprises a multi-layered structure to which a variety of roles have been assigned; an understanding of how cocaine affects evoked activity in these different layers may shed light on how drug-associated sensory cues gain control over behavior. The aim of the present study was to examine how cocaine affects whisker sensory responses in different layers of the primary sensory (barrel) cortex. Field potential and multi-unit activity were recorded from the cortex of anesthetized rats using 16 channel linear probes during repetitive (air puff) stimulation of the whiskers. In control conditions (under saline, i.v.), responses strongly adapted to the repeated sensory stimulation. Following an i.v. injection of cocaine (0.5 mg/kg, i.v.), this adaptation was strongly attenuated, giving each stimulus a more equal representation and weight. Attenuation of adaptation was more marked in the upper cortical layers in both field potential and multi-unit data. Indeed, in these layers, not only was adaptation attenuated but multi-unit response amplitudes under cocaine exceeded those under saline for stimuli occurring early in the train.
The results extend our previous findings concerning the enhancement by cocaine of primary sensory responses. Insofar as enhanced neural responses equate to enhanced stimulus salience, the results indicate that cocaine may play a previously under-appreciated role in the formation of associations between drug and drug-related environmental cues by enhancing stimulus salience. The associative process itself may be assisted by a preferential action in the upper cortical layers, thought to be involved in learning and plasticity.
Neurophysiological evidence for context-dependent encoding of sensory input in human auditory cortex
2006, Brain Research
Citation Excerpt :
The relative contribution of stimulus-driven and attentional processes in organizing the memory representation of the acoustic environment is controversial. There is clear evidence that attention biases response properties of neurons within sensory cortices, indicating that the neural mechanisms of attention modulate the stimulus-driven processes (Bushnell et al., 1981; Chapin and Woodward, 1981; Chelazzi et al., 1993; Desimone, 1998; Hocherman et al., 1976; Hubel et al., 1959; Jancke et al., 1999; Luck et al., 1997; Moran and Desimone, 1985; Nelson et al., 1991; Petkov et al., 2004; Woodruff et al., 1996). In humans, attended sounds evoke enhanced scalp-recorded electrical responses when compared to the responses elicited by unattended sounds (Hillyard et al., 1973).
Attention biases the way in which sound information is stored in auditory memory. Little is known, however, about the contribution of stimulus-driven processes in forming and storing coherent sound events. An electrophysiological index of cortical auditory change detection (mismatch negativity [MMN]) was used to assess whether sensory memory representations could be biased toward one organization over another (one or two auditory streams) without attentional control. Results revealed that sound representations held in sensory memory biased the organization of subsequent auditory input. The results demonstrate that context-dependent sound representations modulate stimulus-dependent neural encoding at early stages of auditory cortical processing.
