Nice feature of our lab's work on infantile amnesia at @tcddublin.

Also of the labs of @SarahDPower @WB_Markus at @mpib_berlin, @Franklandlab at @SickKidsNews, and Nicholas Turk-Browne at @Yale.

Do you work or study in the fields of psychology, neuroscience, computer science, artificial intelligence, or philosophy?

What does 'representation' mean to you?

We invite you to participate in a brief survey on conceptual questions across fields.

Infantile #amnesia limits our recall of early-life memories, but what is its cellular basis?

@erikasstewart from @RyanLabTCD & @tcddublin reveals that #microglia regulate infant memory retrieval in mice during postnatal development.

Microglia Activity in the Brain Drives Infantile Amnesia in Young Mice

According to the data, when microglia activity in the brain was suppressed, baby mice were better able to recall fearful experiences
