Neuronal Computation Underlying Inference in the Brain — BrainPost | Easy-to-read summaries of the latest neuroscience publications
Post by Cody Walters What’s the science? Decisions often require that we infer relationships we have not directly experienced. While the ability to successfully perform inferential reasoning is critical for adaptation and survival, how the...
Scientists discover what happens in our brains when we make educated guesses
Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life.
Neuronal Computation Underlying Inferential Reasoning in Humans and Mice
In humans and mice, the hippocampus supports inferential reasoning by computing a
prospective code to predict upcoming events, before extracting logical links between
discrete events during rest to form a mnemonic short cut for inferred...

I’m delighted to share out new paper: “Neuronal computation underlying inferential reasoning in humans and mice”, out now @CellCellPress with David Dupret and a fantastic team of co-authors @MRCBNDU and @OxfordWIN @NDCNOxford 1/14

An Integrated Index: Engrams, Place Cells, and Hippocampal Memory
Goode et al. interpret recent work on hippocampal anatomy, physiology, and behavior
through the lens of the hippocampal indexing theory, suggesting that hippocampal engrams
may serve as a memory index to permit flexible reinstatement of previous...

Complementary contributions of non-REM and REM sleep to visual learning
Tamaki et al. measured MRS changes in sleeping humans trained on a visual task. During NREM sleep, learning gains were associated with enhanced visual cortical plasticity that was also seen independent of learning. REM sleep stabilized plasticity...

Nice paper by @tamakimasak18 @NatureNeuro. Tracking the swings and roundabouts of EI balance across sleep suggests: E/I increases in NREM, promoting plasticity and performance gains; E/I decreases in REM, stabilizing learning and reducing interference

As one of Oxford's few black professors, let me tell you why I care about Rhodes | Simukai Chigudu
The city is strewn with tributes to the great of the British empire. The devastation they wreaked is routinely forgotten, says professor of African politics Simukai Chigudu
Prediction and memory: a predictive coding account
The hippocampus is crucial for episodic memory, but it is also involved in online prediction. Evidence suggests that a unitary hippocampal code underl…

Prediction and memory w Ryszard Auksztulewicz @auksz and Karl Friston @FarlKriston. Here we use a predictive coding framework to explore hippocampal-neocortical interactions, characterizing memory recall as a fictive prediction error. sciencedirect.com/science/articl… pic.twitter.com/zCPs3rU6Ec

SpikeForest: reproducible web-facing ground-truth validation of automated neural spike sorters
Spike sorting is a crucial but time-intensive step in electrophysiological studies of neuronal activity. While there are many popular software packages for spike sorting, there is little consensus about which are the most accurate under different...
Memory engrams: Recalling the past and imagining the future
The ability to form memory is an essential trait that allows learning and the accumulation of knowledge. But what is a memory? There has been a long history of searching for the neuronal substrate that forms memory in the brain, and the emerging...

An Emergent Neural Coactivity Code for Dynamic Memory
Coincidental spike discharge amongst distributed groups of neurons is thought to provide an efficient mechanism for encoding percepts, actions and cognitive processes. Short timescale coactivity can indeed bind neurons with similar tuning, giving...

Sexism in the Academy
The problems of misogynist PIs and tepid reference letters may stem from the same root: the widespread assumption that only men can be brilliant. This view is prevalent in the hard sciences, but also in literature, musical composition, and...

Are hormones a “female problem” for animal research?
One of the most deep-seated misconceptions about the human psyche is that men are simple and women are complicated ([ 1 ][1]). Gender psychology scholars trace this belief back to at least the 19th century, when the long-standing view that women...
