Neuromodulator Dynamics Underlying Associative Learning in the Ventral Striatum's Olfactory Tubercle

open access: yesAdvanced Science, EarlyView.
Using fiber photometry and genetically encoded sensors, the dynamic release patterns of four neuromodulators in the olfactory tubercle (OT)—a brain region overlapping with the olfactory cortex and ventral striatum—were systematically monitored in response to external rewards and distinct reward‐associated learning processes.

Pauses in cholinergic interneuron firing exert an inhibitory control on striatal output in vivo

open access: yeseLife, 2018
The cholinergic interneurons (CINs) of the striatum are crucial for normal motor and behavioral functions of the basal ganglia. Striatal CINs exhibit tonic firing punctuated by distinct pauses.

Neuromorphic Motor Control with Electrolyte‐Gated Organic Synaptic Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Electrolyte‐gated organic synaptic transistor (EGOST)‐based neuromorphic motor control systems integrate sensing, processing, and actuation by mimicking biological synapses. With advantages such as low power consumption, tunable synaptic plasticity, and mechanical flexibility, they are emerging as next‐generation core technologies for real‐time ...

Ciliomotor circuitry underlying whole-body coordination of ciliary activity in the Platynereis larva

open access: yeseLife, 2017
Ciliated surfaces harbouring synchronously beating cilia can generate fluid flow or drive locomotion. In ciliary swimmers, ciliary beating, arrests, and changes in beat frequency are often coordinated across extended or discontinuous surfaces.

Association of age at pancreatic cancer diagnosis with smoking and drinking: A hospital‐based and meta‐analysis study

open access: yesAdvances in Digestive Medicine, EarlyView.
Abstract Recent trends show an alarming rise in pancreatic cancer prevalence among young individuals. Previous studies have presented differences in age at diagnosis. The study aimed to examine the likelihood of a younger age at diagnosis in individuals exposed to known risk factors, compared with those without exposure.

Neurotransmitter regulation of neural development: acetylcholine and nicotinic receptors

open access: yesAnais da Academia Brasileira de Ciências, 2002
Several neurotransmitter systems have been related to developmental processes during the past decade. In this review, we discuss the evidence that the nicotinic acetylcholine receptors could have an additional function during development that may be ...

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]

open access: yes, 1982
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

open access: yesAdvanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...
