Role of spontaneous and sensory orexin network dynamics in rapid locomotion initiation

Mahesh M. Karnani et al.
Progress In Neurotechnology | February 11, 2020
Appropriate motor control is critical for normal life, and requires hypothalamic hypocretin/orexin neurons (HONs). HONs are slowly regulated by nutrients, but also display rapid (subsecond) activity fluctuations in...

Opposing Somatic and Dendritic Expression of Stimulus-Selective Response Plasticity in Mouse Primary Visual Cortex

Taekeun Kim et al.
Frontiers in Cellular Neuroscience | January 14, 2020
Daily exposure of awake mice to a phase-reversing visual grating stimulus leads to enhancement of the visual-evoked potential (VEP) in layer 4 of the primary visual cortex (V1). This stimulus-selective response...

Revealing neural correlates of behavior without behavioral measurements

Alon Rubin et al.
Nature Communications | October 18, 2019
Measuring neuronal tuning curves has been instrumental for many discoveries in neuroscience but requires a priori assumptions regarding the identity of the encoded variables. We applied unsupervised learning to...

Cortical ensemble activity discriminates auditory attentional states

Pan-tong Yao et al.
Molecular Brain | October 17, 2019
Selective attention modulates sensory cortical activity. It remains unclear how auditory cortical activity represents stimuli that differ behaviorally. We designed a cross-modality task in which mice made decisions to...

Transitioning between preparatory and precisely sequenced neuronal activity in production of a skilled behavior

Vamsi K Daliparthi et al.
eLife | June 11, 2019
Precise neural sequences are associated with the production of well-learned skilled behaviors. Yet, how neural sequences arise in the brain remains unclear. In songbirds, premotor projection neurons in the cortical song...

A hypothalamus-habenula circuit controls aversion

Iakovos Lazaridis et al.
Molecular Psychiatry | February 12, 2019
Encoding and predicting aversive events are critical functions of circuits that support survival and emotional well-being. Maladaptive circuit changes in emotional valence processing can underlie the pathophysiology of...

An amygdalar neural ensemble that encodes the unpleasantness of pain

Gregory Corder et al.
Science | January 17, 2019
Pain is an unpleasant experience. How the brain’s affective neural circuits attribute this aversive quality to nociceptive information remains unknown. By means of time-lapse in vivo calcium imaging and neural...

Touch and Tactile Neuropathic Pain Sensitivity Are Set by Corticospinal Projections

Yuanyuan Liu et al.
Nature | September 12, 2018
Current models of somatosensory perception emphasize transmission from primary sensory neurons to the spinal cord and on to the brain1,2,3,4. Mental influence on perception is largely assumed to occur locally within the...

Dorsal tegmental dopamine neurons gate associative learning of fear

Florian Groessl et al.
Nature Neuroscience | June 27, 2018
Functional neuroanatomy of Pavlovian fear has identified neuronal circuits and synapses associating conditioned stimuli with aversive events. Hebbian plasticity within these networks requires additional reinforcement to...

Stress peptides sensitize fear circuitry to promote passive coping

Pinelopi Pliota et al.
Molecular Psychiatry | June 18, 2018
Survival relies on optimizing behavioral responses through experience. Animals often react to acute stress by switching to passive behavioral responses when coping with environmental challenge. Despite recent advances...

Tracking the Same Neurons across Multiple Days in Ca2+ Imaging Data

Liron Sheintuch et al.
Cell Reports | November 24, 2017
Ca2+ imaging techniques permit time-lapse recordings of neuronal activity from large populations over weeks. However, without identifying the same neurons across imaging sessions (cell registration), longitudinal...

The central amygdala controls learning in the lateral amygdala

Kai Yu et al.
Nature Neuroscience | October 23, 2017
Experience-driven synaptic plasticity in the lateral amygdala is thought to underlie the formation of associations between sensory stimuli and an ensuing threat. However, how the central amygdala participates in such a...
