A general model of hippocampal and dorsal striatal learning and decision making
Humans and other animals use multiple strategies for making decisions. Reinforcement-learning
theory distinguishes between stimulus–response (model-free; MF) learning and …

[HTML][HTML] Dopaminergic action prediction errors serve as a value-free teaching signal
Choice behaviour of animals is characterized by two main tendencies: taking actions that led
to rewards and repeating past actions 1 , 2 . Theory suggests that these strategies may be …

[HTML][HTML] Linking canonical microcircuits and neuronal activity: Dynamic causal modelling of laminar recordings
Neural models describe brain activity at different scales, ranging from single cells to whole
brain networks. Here, we attempt to reconcile models operating at the microscopic (…

Determination of calcium ion activities in milk with an ion-selective electrode. A linear relationship between the logarithm of time and the recovery of the calcium ion …
JP Geerts, JJ Bekhof, JW Scherjon - 1983 - cabidigitallibrary.org
Ca 2+ activity of bulk skim milk varied seasonally from 0.81 to 0.92 mmol/l. It increased on
addition of sucrose. It decreased on heat treatment but increased again linearly with ln time …

Why not record from every electrode with a CMOS scanning probe?
It is an uninformative truism to state that the brain operates at multiple spatial and temporal
scales, each with each own set of emergent phenomena. More worthy of attention is the point …

Probabilistic successor representations with Kalman temporal differences
The effectiveness of Reinforcement Learning (RL) depends on an animal's ability to assign
credit for rewards to the appropriate preceding stimuli. One aspect of understanding the …
