Different levels of food restriction reveal genotype-specific differences in learning a visual discrimination task.

open access: yesPLoS ONE, 2012
In behavioural experiments, motivation to learn can be achieved using food rewards as positive reinforcement in food-restricted animals. Previous studies reduce animal weights to 80-90% of free-feeding body weight as the criterion for food restriction ...

Recurrent network model for learning goal-directed sequences through reverse replay

open access: yeseLife, 2018
Reverse replay of hippocampal place cells occurs frequently at rewarded locations, suggesting its contribution to goal-directed path learning. Symmetric spike-timing dependent plasticity (STDP) in CA3 likely potentiates recurrent synapses for both ...
