We use high refresh rate "gaming" monitors to present closed-loop visual stimuli with low latency. They have various "gaming modes" and response time options that are poorly documented. So
@antblot.bsky.social
tested every possible setting to find out what they do.

Which gaming mode will please my mice?
We use VR setups, see for instance this study, which require fast monitors. We recently got some cheap gaming monitors from MSI

How does the brain blend what we see with what we hear? In collaboration with
@flor-iacaruso.bsky.social
lab, we find new anatomical and functional rules that govern how auditory and visual cortices talk to each other. Led by

Agree. Cuts in UKRI funded PhD places, is about government funding and prioritisation. We need work force planning with joined up thinking A PhD is not about an academic career, its an apprenticeship for the knowledge economy. "Europe's Silicon Valley" will not exist without PhDs

Mouse cortical neurons have ~5,000 spines, but how many different presynaptic cells do they get input from? What is the average number of synaptic contacts between connected neurons in the mouse neocortex? I was hoping that there is a good estimate based on EM but I cannot find one.

Delighted to see this in print from my @TheCrick colleagues in Jonny Kohl's lab How pregnancy (in mice) changes the behaviour of a population of hypothalamic neurons & initiates parental behaviour before birth

Hormone-mediated neural remodeling orchestrates parenting onset during pregnancy
Work in mice suggests that hormonal remodeling of distinct hypothalamic neurons during pregnancy promotes parental behavior.
