Lasting Increases in Neuronal Activity and Serotonergic Receptor Expression Following Gestational Chlorpyrifos Exposure

This study shows that gestational chlorpyrifos exposure increases neuronal activity and 5-HT1B receptor expression in rat somatosensory cortex, leading to persistent hyper-excitation.

Nicotinic Modulation of Fast-spiking Neurons in Rat Somatosensory Cortex Across Development

The paper investigates nicotinic receptor responses in fast-spiking neurons of rat somatosensory cortex across development, finding presynaptic regulation but no postsynaptic responses despite receptor expression.

Gestational Chlorpyrifos Exposure Imparts Lasting Alterations to the Rat Somatosensory Cortex

This study shows that gestational chlorpyrifos exposure causes lasting synaptic and structural changes in the rat somatosensory cortex, potentially explaining neurodevelopmental issues.

Parabrachial nucleus activity in nociception and pain in awake mice

This study tracks parabrachial nucleus neuronal activity in awake mice during pain and shows it correlates with arousal and can be conditioned to respond to innocuous stimuli.
