HUMPHRIES LAB
We are a neural data lab
THE HUMPHRIES LAB
We interrogate how the joint activity of many neurons encodes the past, present, and future in order to guide behaviour. We develop neural data analysis techniques, and use them to understand what joint activity is encoding in recordings of hundreds or thousands of neurons, from across different tasks, brain circuits, species, and phyla. And we develop theoretical and computational models for how this joint activity arises from neural circuits.

The Spike: An Epic Journey Through the Brain in 2.1 Seconds
March 2021
Mark's new book "The Spike" is out now, published by Princeton University Press. Available in hardback, ebook, and audiobook!
It tells the journey of a spike through your brain, from the eye to hand and everywhere in between. And the journey of the last 30 years of systems neuroscience - of all the things we now know about spikes, and the mysteries we've yet to solve.
New paper on population plasticity in the prefrontal cortex
May 2019
Our new paper "Medial Prefrontal Cortex Population Activity Is Plastic Irrespective of Learning" by Singh, Peyrache & Humphries is out in the Journal of Neuroscience.
Here we show, in a trial-and-error task, that population activity in PFC is persistently changing, regardless of learning. Only during episodes of clear learning of relevant actions are the accompanying changes to population activity carried forward into sleep, suggesting a long-lasting form of neural plasticity.

New paper: learning to remember in prefrontal cortex
June 7, 2018
Our new paper in Nature Communications, "An ensemble code in medial prefrontal cortex links prior events to outcomes during learning" reveals how the PfC's roles in learning and short-term memory intersect. Led by Silvia Maggi, and in collaboration with Adrien Peyrache.

New review of modelling Parkinson's disease
April 18, 2018
In our new paper, we review what computational models have taught us about Parkinson's disease. With Jose Obeso and Jakob Dreyer, for the BMJ's Journal of Neurology, Neurosurgery & Psychiatry.
New paper in PLoS Computational Biology
April 10, 2018
Our paper "A probabilistic, distributed, recursive mechanism for decision-making in the brain" led by Javier Caballero is out! Find out how the brain makes decisions between more than two alternatives.

The Humphries lab has landed at the University of Nottingham. Au revoir to our friends at the University of Manchester.
A manifesto for neural data science
March 26, 2018
The neural data scientist uses data from systems neuroscience experiments to ask: how do all these neurons work together to do their thing? This latest post on The Spike is a guide for how to answer this question.

Our #scicomm publication at Medium. We essay the latest advances in understanding of neurons work together. And take a deep dive into the philosophy of systems neuroscience — of how best to understand the brain, and of the limits to our understanding.
