cover story in July 2017 Sci American on &nbsp;Memory &nbsp;(and CREB)</p>

<p>

Key idea: &nbsp;(mouse expts);</p>

<p>

CREB gene when up regulated, increases production of CREB protein which

regulates &nbsp;several other genes, which in turn,

spur the making of ion channels that make that neuron more excitable.</p>

<p>

Those particular neurons that are excited during an experience are more apt to

have synapses strengthened &nbsp;(a la Hebbs rule).</p>

<p>

Key expt: &nbsp;mice exposed to two different cages within 5 hours on the same day

will link those cages in memory... so they will freeze in the 2nd cage... even tho

they did not get a foot shock there but only in the first cage.

This does NOT happen when the experiences in the two different cages are separated by 7 days.</p>

<p>

elaborate controls using optogenetics and DREDD.</p>
