Inhibition of Indirect Pathway Activity Causes Abnormal Decision-Making In a Mouse Model of Impulse Control Disorder in Parkinson’s Disease

Posted by dbos November 1, 2024November 11, 2024UCSF

Kavli Affiliate: Alexandra Nelson | Authors: Xiaowen Zhuang, Julia Lemak, Sadhana Sridhar and Alexandra B Nelson | Summary: Summary: Healthy action selection relies on the coordinated activity of striatal direct and indirect pathway neurons. In Parkinson’s disease (PD), in which loss of midbrain dopamine neurons is associated with progressive motor and cognitive deficits, this coordination […]

Striatal lateral inhibition regulates action selection in a mouse model of levodopa-induced dyskinesia

Posted by dbos November 1, 2024November 11, 2024UCSF

Kavli Affiliate: Alexandra Nelson | Authors: Emily L Twedell, Chloe J Bair-Marshall, Allison E Girasole, Lara K Scaria, Sadhana Sridhar and Alexandra B Nelson | Summary: Summary: Striatal medium spiny neurons (MSNs) integrate multiple external inputs to shape motor output. In addition, MSNs form local inhibitory synaptic connections with one another. The function of striatal […]

Sex chromosome gene expression associated with vocal learning following hormonal manipulation in female zebra finches

Posted by klaurent October 28, 2024November 11, 2024Rockefeller

Kavli Affiliate: Erich Jarvis | Authors: Matthew Davenport, Ha Na Choe, Hiroaki Matsunami and Erich D Jarvis | Summary: Zebra finches are sexually dimorphic vocal learners. Males learn to sing by imitating mature conspecifics, but females do not. Absence of song in females is associated with atrophy and apparent repression of several vocal learning brain […]

A circuit model for transsaccadic space updating and mislocalization

Posted by dbos October 28, 2024November 11, 2024Columbia

Kavli Affiliate: Michael Goldberg | Authors: Xiao Wang, Sophia Tsien, Michael E. Goldberg, Mingsha Zhang and Ning Qian | Summary: We perceive a stable, continuous world despite drastic changes of retinal images across saccades. However, while persistent objects in daily life appear stable across saccades, stimuli flashed around saccades can be grossly mislocalized. We address […]
