Pavlovian auditory fear conditioning involves the integration of information about an acoustic conditioned stimulus (CS) and an aversive unconditioned stimulus in the lateral nucleus of the amygdala (LA). The auditory CS reaches the LA subcortically via a direct connection from the auditory thalamus and also from the auditory association cortex itself. How neural modulators, especially those ac...

Active sensing and sensorymotor loops Sensation is an active process whereby sensory organs continuously and actively sample the external world, usually by physical movements. Thus, to acquire meaningful information about the surrounding, the brain must integrate sensory signals with information about the active movement that induced them. We study how sensor motion and sensory signals interact...

The basal ganglia are involved in sensorimotor functions and action selection, both of which require the integration of sensory information. In order to determine how such sensory inputs are integrated, we obtained whole-cell recordings in mouse dorsal striatum during presentation of tactile and visual stimuli. All recorded neurons responded to bilateral whisker stimulation, and a subpopulation...

Maps of sensory surfaces are a fundamental feature of sensory cortical areas of the brain. The relative roles of afferents and targets in forming neocortical maps in higher mammals can be examined in ferrets in which retinal inputs are directed into the auditory pathway. In these animals, the primary auditory cortex contains a systematic representation of the retina (and of visual space) rather...

OBJECTIVES Restricted sensory syndrome provides an excellent chance for the understanding of neuroanatomic correlation. The trigeminal nerve has been shown to convey buccal sensory impulse to central compartment. However, the pathway between cortex and the trigeminal sensory nucleus remains largely unknown. METHOD A patient presented with cheirobuccopedal syndrome, or objective sensory impair...

Detection and appropriate reaction to sudden and intense events happening in the sensory environment is crucial for survival. By combining Bayesian model selection with dynamic causal modeling of functional magnetic resonance imaging data, a novel analysis approach that allows inferring the causality between neural activities in different brain areas, we demonstrate that salient sensory informa...

Abstract Sensory perception and metabolic homeostasis are known to deteriorate with ageing, impairing the health of aged animals, while mechanisms underlying their deterioration remain poorly understood. The potential interplay between declining sensory impaired metabolism during ageing is also barely explored. Here, we report that intraflagellar transport (IFT) in cilia neurons nematode Caenor...

Many organisms use multimodal maps to generate coherent neuronal representations that allow adequate responses to stimuli that excite several sensory modalities. During ontogeny of these maps, one modality typically acts as the dominant system the other modalities are aligned to. A well studied model for the alignment of sensory maps is the calibration of the auditory space map by the visual sy...

PURPOSE OF REVIEW The present review was undertaken in order to summarize and evaluate recent research investigating taste exposure, sensory learning, and nutrition education interventions for promoting vegetable intake in preschool children. RECENT FINDINGS Overall, taste exposure interventions yielded the best outcomes for increasing vegetable intake in early childhood. Evidence from sensor...

Acoustically interacting males of the tropical katydid Mecopoda elongata synchronize their chirps imperfectly, so that one male calls consistently earlier in time than the other. In choice situations, females prefer the leader signal, and it has been suggested that a neuronal mechanism based on directional hearing may be responsible for the asymmetric, stronger representation of the leader sign...
