WebJan 29, 2024 · A bump attractor network is a model that implements a competitive neuronal process emerging from a spike pattern related to an input source. Since the bump network could behave in many ways, this ... WebJan 26, 2024 · A common hypothesis is that the information is maintained in a bump attractor’s state. We test the bump attractor hypothesis and find that its predictions are inconsistent with the path integration behaviour of ants, thus highlighting the need for alternative models of path integration memory.
A computational model for preplay in the hippocampus
WebMay 24, 2024 · Hello, I Really need some help. Posted about my SAB listing a few weeks ago about not showing up in search only when you entered the exact name. I pretty … WebWhat I observe in my simulations are 'bump' attractors that appear, disappear, and may wander around. Here is a screen shot from a simulation: Dark blue dots represent excitatory neurons' spikes (fading into white to leave a trace), and dark red triangles representing inhibitory neurons' spikes. deadline for filing taxes 2021 india
Subdiffusive Dynamics of Bump Attractors: Mechanisms …
WebWe show that this representation can be implemented in a neural attractor network model, resulting in bump-like activity profiles resembling those of the CA3 region of hippocampus. Neurons tend to locally excite neurons with similar place field centers, while inhibiting other neurons with distant place field centers, such that stable bumps of ... WebOct 4, 2024 · With the reduced model in hand, we can then approximate the dynamics of the bump position using a continuous time Markov chain model that describes bump motion … WebAug 9, 2024 · It is shown that a continuous attractor network can integrate a circular stimulus feature and track the stimulus average in the phase of its activity bump, and that the nonlinear internal dynamics affect the temporal weighting of sensory evidence. Perceptual decision and continuous stimulus estimation tasks involve making judgments … deadline for filing t4 summary
