Topic: Subparafascicular Thalamic Nucleus

Soft touch stimulation can be decoded as positive tactile information, though little is known about the neurobiological brain mechanisms involved. The Subparafascicular Thalamic Nucleus (SPF) receives input from the spinal dorsal horn and sends projections to brain regions processing the affective component of pain such as the amygdala and insular cortex. Recent studies have suggested that SPF act as a gate of threatening cues and is important for aversive learning (Kang et al., Cell Reports, 2022). Here, we investigated if the SPF is also involved in positive aspects of sensory processing, su
