Aeon: an open-source platform to study the neural basis of ethological behaviours over naturalistic timescales Open
Ethological behaviours are a powerful tool for neuroscience since they leverage the robust neural computations shaped by the species’ evolution to study the neural basis of cognitive functions. However, such behaviours are often transitory…

Innate heuristics and fast learning support escape route selection in mice Open
When faced with imminent danger, animals must rapidly take defensive actions to reach safety. Mice can react to threatening stimuli in ∼250 milliseconds1 and, in simple environments, use spatial memory to quickly escape to shelter.2,3 Natu…

### Dataset structure Each experimental session (from one mouse on one arena) was composed of one or more recording. Each recording was saved as a separate video and as such the tracking data and stimuli metadata are saved separately for e…

Summary When faced with imminent danger, animals must rapidly take defensive actions to reach safety. Mice can react to innately threatening stimuli in less than 250 milliseconds [1] and, in simple environments, use spatial memory to quick…

The retrosplenial cortex combines internal and external cues to encode head velocity during navigation Open
The extent to which we successfully navigate the environment depends on our ability to continuously track our heading direction and speed. Angular head velocity (AHV) cells, which encode the speed and direction of head turns during navigat…

Mice learn multi-step routes by memorizing subgoal locations Open
The behavioral strategies that mammals use to learn multi-step routes in natural settings are unknown. Here we show that mice spontaneously adopt a subgoal memory strategy. We first investigated how mice navigate to shelter in response to …

A cortico-collicular circuit for accurate orientation to shelter during escape Open
SUMMARY When faced with predatorial threats, escape towards shelter is an adaptive action that offers long-term protection against the attacker. From crustaceans to mammals, animals rely on knowledge of safe locations in the environment to…

A system for tracking whisker kinematics and whisker shape in three dimensions Open
Quantification of behaviour is essential for biology. Since the whisker system is a popular model, it is important to have methods for measuring whisker movements from behaving animals. Here, we developed a high-speed imaging system that m…

Sensing the Environment With Whiskers Open
Whiskers (vibrissae) are prominent on the snout of many mammals, both terrestrial and aquatic. The defining feature of whiskers is that they are rooted in large follicles with dense sensory innervation, surrounded by doughnut-shaped blood …

Prediction of Choice from Competing Mechanosensory and Choice-Memory Cues during Active Tactile Decision Making Open
Perceptual decision making is an active process where animals move their sense organs to extract task-relevant information. To investigate how the brain translates sensory input into decisions during active sensation, we developed a mouse …

What the Whiskers Tell the Brain Open
A fundamental question in the investigation of any sensory system is what physical signals drive its sensory neurons during natural behavior. Surprisingly, in the whisker system, it is only recently that answers to this question have emerg…

The peripheral olfactory code in <i>Drosophila</i> larvae contains temporal information and is robust over multiple timescales Open
We studied the electrophysiological activity of two classes of Drosophila melanogaster larval olfactory sensory neurons (OSNs), Or24a and Or74a, in response to 1 s stimulation with butanol, octanol, 2-heptanone, and propyl acetate. Each od…

Prediction of primary somatosensory neuron activity during active tactile exploration Open
Primary sensory neurons form the interface between world and brain. Their function is well-understood during passive stimulation but, under natural behaving conditions, sense organs are under active, motor control. In an attempt to predict…
