Pumping the brakes on RNA velocity – understanding and interpreting RNA velocity estimates

Kavli Affiliate: Loyal Goff | Authors: Shijie C. Zheng, Genevieve Stein-O’Brien, Leandros Boukas, Loyal A Goff and Kasper D Hansen | Summary: RNA velocity analysis of single cells promises to predict temporal dynamics from gene expression. Indeed, in many systems, it has been observed that RNA velocity produces a vector field that qualitatively reflects known […]

Targeted cortical stimulation reveals principles of cortical contextual interactions

Kavli Affiliate: Kenneth Miller | Authors: Shen Wang, Agostina Palmigiano, Kenneth D Miller and Stephen David Van Hooser | Summary: Cross-orientation suppression is a classic form of contextual normalization in visual cortex, yet the degree to which cortical circuits participate in the normalization computation is unclear. We visualized orientation maps of individual ferrets, and provided […]

Dynamic top-down biasing implements rapid adaptive changes to individual movements

Kavli Affiliate: Michael Brainard | Authors: Lucas Y Tian, Timothy L Warren and Michael S Brainard | Summary: Complex behaviors depend on the coordinated activity of neural ensembles in interconnected brain areas. The behavioral function of such coordination, often measured as co-fluctuations in neural activity across areas, is poorly understood. One hypothesis is that rapidly […]

Phencyclidine and methamphetamine cause cognitive deficits by changing pyramidal neuron transmitter identity in the prefrontal cortex

Kavli Affiliate: Nicholas Spitzer | Authors: Marta Pratelli, Arth Thaker, Huiquan Li, Swetha Godavarthi and Nicholas C. Spitzer | Summary: Decreased cognitive ability is a major consequence of exposure to drugs of abuse, but the underlying neuroplastic changes have been elusive. We show that both phencyclidine and methamphetamine cause a population of prelimbic pyramidal neurons […]

Sex-specific age-related changes in excitatory and inhibitory intra-cortical circuits in mouse primary auditory cortex

Kavli Affiliate: Patrick Kanold | Authors: Binghan Xue, Joseph P-Y Kao and Patrick O Kanold | Summary: A common impairment in aging is age-related hearing loss (presbycusis), which manifests as impaired spectrotemporal processing. Aging is accompanied by alteration in normal inhibitory (GABA) neurotransmission and changes in excitatory (NMDA and AMPA) synapses in the auditory cortex […]
