Neuroscientists based at the Sainsbury Wellcome Centre for Neural Circuits and Behaviour in London, Danbee Kim and Adam R Kampff study how the brain builds a mental model of its environment. Here, they imagine ‘built environments’ derived from these mental models. Their proposed designs may be ugly and they will likely fall over, but they hope they will distil insights from neuroscientific research...
The concept of affordances facilitates the encoding of relations between actions and effects in an environment centered around the agent. Such an interpretation has important impacts on several cognitive capabilities and manifestations of intelligence, such as prediction and planning. In this paper, a new framework based on denoising Auto-encoders (dA) is proposed which allows an agent to explore...
Motor cortex is widely believed to underlie the acquisition and execution of motor skills, but its contributions to these processes are not fully understood. One reason is that studies on motor skills often conflate motor cortex’s established role in dexterous control with roles in learning and producing task-specific motor sequences. To dissociate these aspects, we developed a motor task for rats...
The function of the motor cortex has been a persistent mystery. A recent study has found striking correspondence between the descending projections of lamprey pallium and mammalian motor cortex, encouraging comparative studies of the origin (and role) of forebrain motor control.
The precise temporal relation between pre- and postsynaptic activity modulates the strength of synaptic connections. Despite its extensive characterization in vivo and in vitro, the degree to which spike timing-dependent plasticity can shape receptive field properties is unclear. We use in vivo patch-clamp recordings of tectal neurons in developing Xenopus tadpoles to control the precise timing of...
