Minamisawa G, Dong M, OConnor D
bioRxiv
. 2024 Dec;
PMID: 39713341
Somatosensory cortex activity relates both to sensation and movement, reflecting their intimate relationship, but the extent and nature of sensory-motor interactions in the somatosensory cortex remain unclear. Here, we investigated...

Olson W, Chokshi V, Kim J, Cowan N, OConnor D
bioRxiv
. 2024 Sep;
PMID: 39345532
Sensory feedback is essential for motor performance and must adapt to task demands. Muscle spindle afferents (MSAs) are a major primary source of feedback about movement, and their responses are...

Zhang L, Nagel M, Olson W, Chesler A, OConnor D
Cell Rep
. 2024 Aug;
43(9):114665.
PMID: 39215998
The neural basis of tongue mechanosensation remains largely mysterious despite the tongue's high tactile acuity, sensitivity, and relevance to ethologically important functions. We studied terminal morphologies and tactile responses of...

Kim J, Wyche I, Olson W, Lu J, Bakir M, Sober S, et al.
bioRxiv
. 2024 Jul;
PMID: 38979246
Complex movements involve highly coordinated control of local muscle elements. Highly controlled perturbations of motor outputs can reveal insights into the neural control of movements. Here we introduce an optogenetic...

. 2024 Jun;
12.
PMID: 38842277
Flexible responses to sensory stimuli based on changing rules are critical for adapting to a dynamic environment. However, it remains unclear how the brain encodes and uses rule information to...

Finkel E, Chang Y, Dasgupta R, Lubin E, Xu D, Minamisawa G, et al.
Cell Rep
. 2024 Apr;
43(4):113991.
PMID: 38573855
The brain receives constant tactile input, but only a subset guides ongoing behavior. Actions associated with tactile stimuli thus endow them with behavioral relevance. It remains unclear how the relevance...

Neuroscience
. 2024 Mar;
544:128-137.
PMID: 38447690
In Robo3cKO mice, midline crossing defects of the trigeminothalamic projections from the trigeminal principal sensory nucleus result in bilateral whisker maps in the somatosensory thalamus and consequently in the face...

STAR Protoc
. 2023 Dec;
5(1):102785.
PMID: 38127625
An extensive literature describes how pupil size reflects neuromodulatory activity, including the noradrenergic system. Here, we present a protocol for the simultaneous recording of optogenetically identified locus coeruleus (LC) units...

Curr Biol
. 2023 Nov;
33(22):R1203-R1205.
PMID: 37989101
Muscular hydrostats, such as the elephant trunk, can perform precise motor actions. A new study has revealed that the elephant trunk contains a dense network of tiny muscle fascicles, suggesting...

PMID: 37757586
Orofacial motor actions are movements that, in rodents, involve whisking of the vibrissa, deflection of the nose, licking and lapping with the tongue, and consumption through chewing. These actions, along...
