Cholinergic feedback for context-specific modulation of sensory representations

Kavli Affiliate: Takaki Komiyama | Authors: Bin Yu, Yuxuan Yue, Chi Ren, Rui Yun, Byungkook Lim and Takaki Komiyama | Summary: The brain’s ability to prioritize behaviorally relevant sensory information is crucial for adaptive behavior, yet the underlying mechanisms remain unclear. Here, we investigated the role of basal forebrain cholinergic neurons in modulating olfactory bulb […]

Brain state and cortical layer-specific mechanisms underlying perception at threshold

Kavli Affiliate: Anirvan Nandy, John Reynolds | Authors: Mitchell P Morton, Sachira Denagamage, Isabel J Blume, John H Reynolds, Monika P Jadi and Anirvan S Nandy | Summary: Identical stimuli can be perceived or go unnoticed across successive presentations, producing divergent behavioral outcomes despite similarities in sensory input. We sought to understand how fluctuations in […]

Multiple and subject-specific roles of uncertainty in reward-guided decision-making

Kavli Affiliate: Angela Yu | Authors: Alexander Paunov, Maëva L’Hôtellier, Zoe He, Dalin Guo, Angela Yu and Florent Meyniel | Summary: Decision-making in noisy, changing, and partially observable environments entails a basic tradeoff between immediate reward and longer-term information gain, known as the exploration-exploitation dilemma. Computationally, an effective way to balance this tradeoff is by […]

Neuromodulators generate multiple context-relevant behaviors in a recurrent neural network by shifting activity flows in hyperchannels

Kavli Affiliate: Kay Tye and Terrence Sejnowski | Authors: Ben Tsuda, Stefan C Pate, Kay M Tye, Hava T Siegelmann and Terrence J Sejnowski | Summary: Neuromodulators are critical controllers of neural states, with dysfunctions linked to various neuropsychiatric disorders. Although many biological aspects of neuromodulation have been studied, the computational principles underlying how neuromodulation […]

A STING-CASM-GABARAP Pathway Activates LRRK2 at Lysosomes

Kavli Affiliate: Shawn Ferguson | Authors: Amanda Bentley-DeSousa and Shawn Ferguson | Summary: Mutations that increase LRRK2 kinase activity have been linked to Parkinson’s disease and Crohn’s disease. LRRK2 is also activated by lysosome damage evoked by chemical and pathogenic stimuli. However, the endogenous cellular mechanisms that control LRRK2 kinase activity are not well understood. […]
