No consistent startle modulation by reward

Scientific Reports, 2021
Previous studies have not clearly demonstrated whether motivational tendencies during reward feedback are mainly characterized by appetitive responses to a gain or mainly by aversive consequences of reward omission.

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

British Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

The effect of ketamine on affective modulation of the startle reflex and its resting-state brain correlates

Scientific Reports, 2023
Ketamine is a rapid-acting antidepressant that also influences neural reactivity to affective stimuli. However, the effect of ketamine on behavioral affective reactivity is yet to be elucidated.

Reflex Epilepsy in Children: Clinical, Electroencephalographic and Brain Magnetic Resonance Imaging Findings [PDF]

International Journal of Medical Arts, 2023
Background: Reflex epilepsy is an epileptic event precipitated by external stimuli such as flashes of light or internal mental process like thinking or calculation and/or associated with photo-paroxysmal response on electroencephalogram [EEG].The Aim of ...

Whole-body prepulse inhibition protocol to test sensorymotor gating mechanisms in monkeys. [PDF]

PLoS ONE, 2014
Prepulse inhibition (PPI) is the decrease of startle reflex amplitude when a slight stimulus is previously generated. This paradigm may provide valuable information about sensorimotor gating functionality.

Effects of melatonin on startle reflex in rat [PDF]

Peptides, 1981
In two experiments the effects of melatonin were investigated on the motor, cardiac and emotional components of the startle reflex induced by an intense acoustic stimulus. Melatonin inhibited the motor movements and significantly decreased the HR responses of rats pretested with these procedures.

A genetically identified population of layer 4 neurons in auditory cortex that contributes to pre-pulse inhibition of the acoustic startle response

Frontiers in Neural Circuits, 2022
A fundamental task faced by the auditory system is the detection of events that are signaled by fluctuations in sound. Spiking in auditory cortical neurons is critical for sound detection, but the causal roles of specific cell types and circuits are ...

A model-based quantification of startle reflex habituation in larval zebrafish

Scientific Reports, 2021
Zebrafish is an established animal model for the reproduction and study of neurobiological pathogenesis of human neurological conditions. The ‘startle reflex’ in zebrafish larvae is an evolutionarily preserved defence response, manifesting as a quick ...

Principles of Electrophysiological Assessments for Movement Disorders [PDF]

Journal of Movement Disorders, 2020
Electrophysiological studies can provide objective and quantifiable assessments of movement disorders. They are useful in the diagnosis of hyperkinetic movement disorders, particularly tremors and myoclonus.

Delays in the Reticulospinal System Are Associated With a Reduced Capacity to Learn a Simulated Feeding Task in Older Adults

Frontiers in Neural Circuits, 2022
Learning declines with age. Recent evidence indicates that the brainstem may play an important role in learning and motor skill acquisition. Our objective was to determine if delays in the reticular formation, measured via the startle reflex, correspond ...
