Cognition without neurons: modelling anticipation in a basal reservoir computer

Polyphony Bruna, Linnea Gyllingberg · 2025

How do non-neural organisms, such as the slime mould \textit{Physarum polycephalum}, anticipate periodic events in their environment? We present a minimal, biologically inspired reservoir model that d…

Effects of synapse location, delay and background stochastic activity on synchronising hippocampal CA1 neurons

Alessandro Fiasconaro, Michele Migliore · 2024

We study the synchronisation of neurons in a realistic model under the Hodgkin-Huxley dynamics. To focus on the role of the different locations of the excitatory synapses, we use two identical neurons…

An Overlooked Role of Context-Sensitive Dendrites

Mohsin Raza, Ahsan Adeel · 2024

To date, most dendritic studies have predominantly focused on the apical zone of pyramidal two-point neurons (TPNs) receiving only feedback (FB) connections from higher perceptual layers and using the…

Geometrical determinant of nonlinear synaptic integration in human cortical pyramidal neurons

Jaeyoung Yoon · 2024

Neurons integrate synaptic inputs and convert them to action potential output at electrically distant locations. The computational power of a neuron is hence enhanced by subcellular compartmentalizati…

Functions of Direct and Indirect Pathways for Action Selection Are Quantitatively Analyzed in A Spiking Neural Network of The Basal Ganglia

Sang-Yoon Kim, Woochang Lim · 2024

We are concerned about action selection in the basal ganglia (BG). We quantitatively analyze functions of direct pathway (DP) and indirect pathway (IP) for action selection in a spiking neural network…

Rethinking the external globus pallidus and information flow in cortico-basal ganglia-thalamic circuits

Cristina Giossi, Jonathan E. Rubin, Aryn Gittis, Timothy Verstynen, Catalina Vich · 2023

For decades the external globus pallidus (GPe) has been viewed as a passive way-station in the indirect pathway of the cortico-basal ganglia-thalamic (CBGT) circuit, sandwiched between striatal inputs…
