Activity of the C. elegans egg-laying behavior circuit is controlled by competing activation and feedback inhibition

open access: yeseLife, 2016
Like many behaviors, Caenorhabditis elegans egg laying alternates between inactive and active states. To understand how the underlying neural circuit turns the behavior on and off, we optically recorded circuit activity in behaving animals while ...

Novel Second-Order Fully Differential All-Pass Filter Using CNTFETs

open access: yesMicromachines, 2023
In this paper, a new carbon nanotube field effect transistor (CNTFET)-based second-order fully differential all-pass filter circuit is presented. The realized filter uses CNTFET-based transconductors and grounded capacitors.

Emergence of Motor Circuit Activity

open access: yesPLoS ONE, 2014
In the developing nervous system, ordered neuronal activity patterns can occur even in the absence of sensory input and to investigate how these arise, we have used the model system of the embryonic chicken spinal motor circuit, focusing on motor neurons of the lateral motor column (LMC).

A wake-active locomotion circuit depolarizes a sleep-active neuron to switch on sleep

open access: yesPLoS Biology, 2020
Sleep-active neurons depolarize during sleep to suppress wakefulness circuits. Wake-active wake-promoting neurons in turn shut down sleep-active neurons, thus forming a bipartite flip-flop switch.

The Active Inductor [A Circuit for All Seasons]

open access: yes, 2020
Reports on the technology of active inductors, inductorless circuits whose impedance rises with frequency across some frequency range. Occupying much less area than a passive inductor and offering tunability, such a circuit proves useful in broadening ...

Active control of arousal by a locus coeruleus GABAergic circuit

open access: yesNature Neuroscience, 2018
Arousal responses linked to locus coeruleus noradrenergic (LC-NA) activity affect cognition. However, the mechanisms that control modes of LC-NA activity remain unknown.

Analysis of active piezoelectric energy harvester

open access: yesJournal of Hebei University of Science and Technology, 2018
Most of the existing piezoelectric traps are designed for a narrow frequency range of vibration, but the surrounding environment has a very wide frequency range, and the frequency may also be subject to change, causing the problem of difficult to achieve

Voltage-Mode Four-Phase Sinusoidal Generator and Its Useful Extensions

open access: yesActive and Passive Electronic Components, 2013
This paper introduces a new voltage-mode second-order sinusoidal generator circuit with four active elements and six passive elements, including grounded capacitors. The frequency and condition of oscillation can be independently controlled.
