Congratulations to Athena Akrami, whose paper in Nature is now out (link here).
In this paper, Athena combined formal algorithmic behavioral analysis, optogenetic inactivations, and electrophysiological recordings in rats to show that Posterior Parietal Cortex (PPC) is specifically involved in the representation and use of prior sensory experience in Parametric Working Memory (PWM) tasks, where rats compare two sequential auditory stimuli, separated by a delay.
Here’s a fantastic News and Views piece by Prof. Laura Busse on Athena’s paper: Working memory freed from the past
Congratulations to graduate student Alex Piet, whose paper in Neural Computation is now out (link here).
In this paper Alex uses two-node attractor network models to figure out what neural mechanisms could lead to FOF (a rat cortical region) contributing to decision-making as the lab found in Erlich et al. eLife 2015 and Erlich et al. Neuron 2011. Alex’s results point to specific mechanisms in which the FOF contributes “post-categorization” memory, and make some predictions that Alex then confirmed as correct in a post-hoc analysis of the data.
Congratulations to ex-graduate student (now Dr.) Kevin Miller, who just had a paper published in Nature Neuroscience, on developing a planning task for rats together with computational methods to analyse the rats’ behavior, and using those to establish a role for the hippocampus in planning. Link to the paper is here.
Congratulations to Ben Scott and Christine Constantinople, co-first authors of a paper in Neuron describing how calcium imaging recordings during accumulation of evidence reveal that evidence is encoded in heterogeneous neural responses that have a wide diversity of timescales.
Congrats to recent Ph.D. graduate Dr. Kevin Miller!!! Kevin was a joint student with Carlos Brody and Matt Botvinick.
Congratulations to graduate student Alex Piet, who just had a paper accepted in Neural Computation on using modeling to distinguish roles of the FOF cortex in decision-making, as well as distinguishing between neural mechanisms by which the FOF could implement a post-categorization memory role. Link to paper will be added when it becomes available.
Congratulations to postdoc Ben Scott (joint with Tank lab), who was named as one of the prestigious Next Generation Leaders of the Allen Institute for Brain Science .
Congratulations to undergrad Cecilia Barowski who advanced to the women’s semifinal in the 800m track and field event at the
US Olympic Trials.
