2022/07/22

What is the nature of autonomic signals and how do they shape introception? This study presents a new method for evaluating cardiac interoceptive ability, measuring sensitivity to naturalistic changes in the number of heartbeats over time periods. The results of this research show participants have an overall tendency towards sensing fewer heartbeats during higher heart rates. This likely reflects the influence of changing heartbeat strength on cardiac interoception at rest, which should be taken

Journal of Neurophysiology ·

2022/03/11

What are the most important classes of anesthetics and their use? Do anesthetics affect GABA-A receptor expression or composition? In this podcast author Dr. Robert Pearce of the University of Wisconsin-Madison discusses these questions and more as he goes over his recent research titled “ Hippocampal β2-GABA-A receptors mediate LTP suppression by etomidate and contribute to long-lasting feedback but not feedforward inhibition of pyramidal neurons” with Editor-in-Chief Prof. Nino Ramirez

The orchestration of the sympathetic response

Journal of Neurophysiology ·

2022/01/21

Most of us have heard about the Flight and Fight response and the activation of the sympathetic system. But, what is often overlooked is the sheer complexity of sympathetic activation as it differentially and specifically modulates different organ systems. Different stressors activate and inhibit specific target organs, including specific muscle groups. Understanding the mechanisms how the central and peripheral nervous system interacts to control such a highly differentiated sympathetic response is

Cerebral palsy (CP) is the most common cause of motor disability in children. People with moderate-to-severe CP are typically non-ambulatory and have major impairments in trunk postural control. Dr. Saavedra has tremendous clinical experience in

In our current society, multimedia use is particularly prevalent. It has become increasingly normal to multitask, which requires cognitive flexibility. How do we focus without getting fatigued at the same time? Would you think that the data on fatigability bears information about possible changes in people with “burnout” or other forms of “fatigue”? What is happening in our brain when we fatigue by pursuing our daily tasks? Author, Professor Christian Beste of Dresden University of Technology
