Plastic Exposure During Pregnancy Hinders Brain Development

Perinatal Exposure to Phthalates Results in Lower Number of Neurons and Synapses in the Medial Prefrontal Cortex

Adult rats that had been exposed before birth and during nursing to a mixture of chemicals found in a wide range of consumer products have a smaller medial prefrontal cortex (mPFC) and perform worse on an attention-switching task than rats not exposed to the chemicals early in life. These findings, published in JNeurosci, demonstrate a long-term influence of endocrine-disrupting compounds on brain development. Kougias et al., JNeurosci (2018)



From Ion Channels to Whole Brain Stimulation


Pores at the surface of neurons and muscle cells control your every thought, movement; the very beating of your heart. The way the pores behave shapes signals in the form of ions moving across the cell surface. For the first time, researchers have mapped the behavior of the largest family of these voltage-gated ion channels: Kv channels.


Kids Need More Sleep, Less Screen, Says HALO Group


A paper published today in Pediatrics suggests that children and youth who do not sleep enough and use screens more than recommended are more likely to act impulsively and make poorer decisions.


Watching the Brain's "Firework Memories"


A new paper a neuronal mechanism central to human free recall that sees orchestrated burst of synchronous activation by about 15% of hippocampal neurons.
