McHaney J, Hancock K, Polley D, Parthasarathy A
Sci Rep
. 2024 Dec;
14(1):30882.
PMID: 39730737
Multi-talker speech intelligibility requires successful separation of the target speech from background speech. Successful speech segregation relies on bottom-up neural coding fidelity of sensory information and top-down effortful listening. Here,...

Polley D, Chambers A
Curr Biol
. 2024 Oct;
34(20):R924-R926.
PMID: 39437729
A new study shows that glutamatergic neurons of the pontine central gray (PCG) play a key role in mediating rapid sound-induced awakenings from sleep by relaying short-latency auditory information to...

Clayton K, McGill M, Awwad B, Stecyk K, Kremer C, Skerleva D, et al.
bioRxiv
. 2024 Jun;
PMID: 38853938
Parvalbumin-expressing inhibitory neurons (PVNs) stabilize cortical network activity, generate gamma rhythms, and regulate experience-dependent plasticity. Here, we observed that activation or inactivation of PVNs functioned like a volume knob in...

Clayton K, Stecyk K, Guo A, Chambers A, Chen K, Hancock K, et al.
Curr Biol
. 2024 Mar;
34(8):1605-1620.e5.
PMID: 38492568
Sound elicits rapid movements of muscles in the face, ears, and eyes that protect the body from injury and trigger brain-wide internal state changes. Here, we performed quantitative facial videography...

Elife
. 2024 Feb;

PMID: 38376907
Basal forebrain cholinergic neurons modulate how organisms process and respond to environmental stimuli through impacts on arousal, attention, and memory. It is unknown, however, whether basal forebrain cholinergic neurons are...

Smith S, Jahn K, Sugai J, Hancock K, Polley D
bioRxiv
. 2024 Jan;
PMID: 38187580
Sound is jointly processed along acoustic and emotional dimensions. These dimensions can become distorted and entangled in persons with sensory disorders, producing a spectrum of loudness hypersensitivity, phantom percepts, and...

Asokan M, Watanabe Y, Kimchi E, Polley D
Cell Rep
. 2023 Sep;
42(10):113167.
PMID: 37742187
The amygdala, cholinergic basal forebrain, and higher-order auditory cortex (HO-AC) regulate brain-wide plasticity underlying auditory threat learning. Here, we perform multi-regional extracellular recordings and optical measurements of acetylcholine (ACh) release...

McHaney J, Hancock K, Polley D, Parthasarathy A
bioRxiv
. 2023 Aug;
PMID: 37645975
Optimal speech perception in noise requires successful separation of the target speech stream from multiple competing background speech streams. The ability to segregate these competing speech streams depends on the...

Hear Res
. 2023 Jul;
437:108854.
PMID: 37487430
Hyperacusis is a debilitating auditory condition whose characterization is largely qualitative and is typically based on small participant cohorts. Here, we characterize the hearing and demographic profiles of adults who...

Neuron
. 2023 Mar;
111(5):601-603.
PMID: 36863318
In this issue of Neuron, Schroeder et al. provide the first functional account of inhibitory signaling from the zona incerta to neocortex in behaving animals. Incertocortical afferents exhibit bidirectional plasticity...
