Developed at the University of Manchester, SpiNNaker is built to mimic the way biological neural networks operate, allowing researchers to study brain-like computations and processes. Key features of SpiNNaker include: 1. **Parallel Processing**: The architecture consists of a large number of simple processing cores (over a million), enabling massive parallel processing capabilities.
Spike-triggered average 1970-01-01
The spike-triggered average (STA) is a method used in computational neuroscience to characterize the relationship between neuronal spike train activity and sensory stimuli. It involves analyzing how specific inputs or stimuli relate to the output of a neuron, particularly the times at which the neuron fires action potentials (or spikes). Here's how it works, step by step: 1. **Data Collection:** A neuron's spiking activity is recorded alongside a sensory stimulus (such as a visual or auditory signal).
Spike-triggered covariance 1970-01-01
Spike-triggered covariance (STC) is a computational technique used in neuroscience to analyze how the spiking activity of a neuron's action potentials (or 'spikes') relates to the sensory stimuli that the neuron receives. The method helps to identify the preferred stimulus features that drive neuron firing. ### Key Concepts of Spike-Triggered Covariance: 1. **Spike Train:** The sequence of spikes emitted by a neuron over time in response to stimuli.
Spike directivity 1970-01-01
Spike directivity refers to a phenomenon in neuroscience, particularly in the context of action potentials and neuronal firing patterns. In simple terms, it describes how the direction of action potential propagation in neurons can influence the way information is transmitted and processed in the nervous system. In more specific contexts, such as in studies of neural coding or synaptic transmission, spike directivity may refer to the alignment and orientation of neuronal activity in relation to the specific inputs they receive.
Spike response model 1970-01-01
The Spike Response Model (SRM) is a type of mathematical model used to describe the dynamics of neuron firing in response to various stimuli. It is particularly relevant in the field of computational neuroscience and serves as a framework for understanding how neurons process inputs and generate output spikes (action potentials). Here are some key characteristics of the Spike Response Model: 1. **Spike Generation**: The model focuses on the timing of spikes, which are the discrete events when a neuron emits an action potential.
Steady state topography 1970-01-01
Steady state topography refers to a theoretical state of landforms where the rate of erosion and the rate of uplift or sediment deposition are balanced over time. In this context, the landscape reaches a dynamic equilibrium such that the overall shape and characteristics of the topography remain relatively constant despite ongoing geological processes. In practice, steady state topography is achieved when the forces that shape the landscape (such as tectonic uplift, erosion by wind or water, and sediment transport) are in equilibrium.
