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.

Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]

open access: yes, 1982
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...

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.

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 ...

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 ...

Wirelessly Powered Soft Magnetic Robot with Microneedle for Electrical Stimulation and Drug Delivery

open access: yesAdvanced Intelligent Systems, EarlyView.
A wirelessly powered soft magnetic robot integrates microneedles to enable dual functions: electrical stimulation (86.7% efficiency at 6 cm, tunable 0–20 V voltage, 0.4–50 ms pulses) and drug delivery. It switches surfaces via magnetic fields for gastrointestinal tract locomotion and treatment, with in vitro validation in fresh pig gut showing ...

Mutations in M2 alter the selectivity of the mouse nicotinic acetylcholine receptor for organic and alkali metal cations [PDF]

open access: yes, 1992
We measured the permeability ratios (PX/PNa) of 3 wild-type, 1 hybrid, 2 subunit-deficient, and 22 mutant nicotinic receptors expressed in Xenopus oocytes for alkali metal and organic cations using shifts in the bi-ionic reversal potential of the ...

Characterization of di‐gital, tri‐gital, and tetra‐gital temporal movement of systolic blood pressure on the arterial pulse waveform of rats at different vascular stiffness

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The example of the time dependent fluctuation of systolic pressure on rat arterial pulse waveform in ms. The four levels of the systolic pressure fluctuation show di‐gital, tri‐gital and tetra‐gital fluctuation. The red dots represent particular heartbeats. Abstract Background An arterial stiffness is an indicator of many cardiovascular diseases.
