This study investigates tactile localization on the breast, areola, and nipple, finding lower precision compared to the hand and back, and highlighting distinct tactile properties of the nipple.

The paper investigates texture coding in higher order somatosensory cortices of macaques, finding that S2/PV neurons represent texture more sparsely and encode task-related information rather than the stimulus itself.

This study compares prehension kinematics between humans and rhesus macaques, finding overall similarity with subtle differences in posture specificity and joint coordination.

The paper characterizes the short-latency neural responses to intracortical microstimulation using a multi-electrode array and describes the temporal dynamics of evoked activity.

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

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.

This paper uses computational modeling to resolve conflicting findings on how intracortical microstimulation (ICMS) intensity affects neural activation, showing increased activation density without increased volume.

The paper was withdrawn due to an error in the data processing pipeline, and the authors do not wish it to be cited.
