Christos Constantinidis @cconstan.bsky.social · 16/09/2026After last year's collapse of NIH funding rates I thought things couldn't get any worse. Shifting to multi-year awards could mean that fewer funds would be needed to pay already active grants in 2026. I was wrong. With less than a month left in the fiscal year we are on pace for a new all time low. 14421

Christos Constantinidis @cconstan.bsky.social · 04/04/2026Decoding of task variables again showed variability and task-specific patterns: improved spatial match-nonmatch task decoding, little change in object match-nonmatch task decoding, and disappearance of a saccade bias in the object choose-match task. (9/10) 101
Christos Constantinidis @cconstan.bsky.social · 04/04/2026Firing rate analysis recapitulated the human studies. There was no consistent change with training beyond a slight trend of increase in baseline; instead, it moved in different directions by task. A significant decrease was present during the choice epoch across tasks (6/10) 101
Christos Constantinidis @cconstan.bsky.social · 04/04/2026We introduce a behavioral metric of progress in task acquisition we term "Drop in Performance" (DIP) at trial reversals. As subjects learned the stimulus-reward rule, DIP magnitude decreased significantly across all subjects and tasks. (4/10) 101

Christos Constantinidis @cconstan.bsky.social · 26/03/2026Incredibly honored to be named a Fellow of the American Association for the Advancement of Science. This distinction recognizes the work of my students and trainees over the years. Congratulations to the other Vanderbilt faculty elected AAAS Fellows as well. 1273
Christos Constantinidis @cconstan.bsky.social · 07/03/2026Very happy to announce that my student Zhengyang Wang successfully defended his dissertation, today. Congratulations Dr. Wang! 060

Christos Constantinidis @cconstan.bsky.social · 29/12/2025When we calculated decoding accuracy of populations of neurons sampled from different trials (or “pseudo-populations”, commonly used in neurophysiology) and tested them with neurons recorded simultaneously, only a subtle performance decrease was evident (12/10) 100
Christos Constantinidis @cconstan.bsky.social · 29/12/2025However, we also show that such off-states are relative decreases in firing rate rather than absolute “gaps” in spiking. Activity across the network continued to maintain information about the stimulus being remembered even during off states (11/10) 110
Christos Constantinidis @cconstan.bsky.social · 29/12/2025In this article we document “The Asynchronous State” of Working Memory. In single trials, individual neurons may not exhibit persistent activity, however populations of ~100 neurons are sufficient to generate activity elevated above the baseline for the entire delay period (8/10) 110

Christos Constantinidis @cconstan.bsky.social · 24/12/2024I have a theory of why Trump wants to buy Greenland. It's the accursed Mercator projection! In most maps Greenland appears much larger than the US and the same size as the entire continent of Africa. In reality, it is about the size of Algeria. I predict Trump would lose interest if he found out. 180

Christos Constantinidis @cconstan.bsky.social · 30/11/2024It's been three weeks since I moved to BlueSky as my go-to social network and it's been a relief to be able to check research news without having Elon's hot take of the day shoved to the top of my feed. At the same time, I've decided not to deactivate my Twitter/X account but continue using it. 141
