The paper demonstrates that tactile suppression is specifically tuned to predicted sensory states of movement, not just unspecific gating.

The paper identifies a developmental switch in information transfer from wS1 to wS2 cortex in mice, showing excitatory connections emerge after the first post-natal week.

The paper investigates how early blindness affects brain networks involved in spatial hearing, finding enhanced motion direction coding in hMT+/V5 and reduced coding in hPT in blind individuals.

The paper investigates whether visual and haptic shape recognition share the same neural processing by comparing performance in shape comparison tasks across modalities.

This study examines cortical hand map changes after finger nerve block, finding persistent representation despite input loss, suggesting distributed processing and homeostatic mechanisms.

The paper shows that newborn infants have widespread nociceptive maps in the somatosensory cortex, aligning with their disorganised pain behaviour.

The paper examines functional and structural changes in the primary motor cortex of a Paralympian with congenital paraplegia compared to controls and other paraplegic athletes.

This study investigates ingestive behavior deficits in Prrxl1 knockout mice, revealing impaired trigeminal pathway function and its impact on orosensory processing across multiple timescales.

The paper distinguishes between predictive attenuation and tactile gating as separate perceptual phenomena by showing they operate independently and are not correlated.

The paper shows that texture is encoded in precise temporal spiking patterns in primate somatosensory cortex, with millisecond precision and perceptual relevance.

The paper shows that body part and action information is distributed across the somatosensory homunculus beyond primary areas, revealing new organizational principles in S1.

The paper shows that tactile pleasure involves both fast A-beta and slow CT signaling in the somatosensory cortex, challenging the traditional divide between discriminative and affective touch.

The paper investigates ipsilateral stimulus encoding in primary and secondary somatosensory cortex of awake mice, finding that S2 encodes ipsilateral stimuli more accurately than S1.

The paper shows humans perceive tactile stimuli as moving across body parts in external space, not just along anatomical boundaries, using a Bayesian model based on Euclidean distance.

The paper shows that in macaque monkeys, the thumb representation in area 3b of the somatosensory cortex is processed in an independent module compared to other digits.

This study maps the paralemniscal vibrissa pathway in rodents, showing it connects to brainstem autonomic regions and forebrain emotional centers, with GABAergic inhibition in the Kolliker-Fuse nucleus.

The paper investigates whether deafferented visual cortices of blind individuals represent common spatial maps of naturalistic auditory stimuli, finding shared cross-subject pattern similarity in visual cortex for meaningful stimuli.

The paper investigates how alpha oscillations contribute to localizing touch on hand-held tools by analyzing EEG data during tactile stimulation tasks.

The paper investigates the distribution and physiological properties of C-tactile afferents in human arm and leg nerves, finding they are more sparse in the lower leg and insensitive to menthol and histamine.

The paper shows that blind individuals' fusiform gyrus responds to human facial expression sounds, linking shape and action, but not to speech or animal sounds.

The paper proposes a neural network model that uses multilateration to decode touch location on the body, showing it matches psychophysical experiments.

This study uses an autoencoder to learn a compressed representation of vibratory patterns from haptic exploration, enabling material classification and revealing similarities to human tactile perception.

The paper investigates whether predictive mechanisms in action reduce or enhance tactile perception, finding that expected touch during action is perceived more intensely than unexpected touch.

The paper investigates tactile signal processing in the cuneate nucleus of macaques and finds that CN neurons exhibit response properties more similar to cortical neurons than to their peripheral inputs.

The paper investigates how respiration and heartbeat influence tactile perception by analyzing timing of stimulation during the cardiac cycle and its effects on detection rates.

The paper investigates how stimulus history influences tactile perception in rats and humans, finding a repulsive effect where past stimuli bias current judgments, and shows this effect can be modeled with a single-parameter decision criterion model.

The paper shows that mouse and human vibro-tactile pitch perception follows a common computational principle involving frequency and amplitude relationships.
