The neuron doctrine: The neuron is the essential constituent of the nervous system and the fundamental unit of perception.
A Neuron is a nerve cell, comprised of a soma (site of signals integration), dendrites (signal input pathways), and axon (signal output pathway). Neurons typically communicate with other neurons with spikes.
The neuron doctrine: The neuron is the essential constituent of the nervous system and the fundamental unit of perception.
Neural coding: Neurons encode information with spikes. Encoding can be based on binary coding (responding when something happens), rate coding (information as a function of spiking rate), time-to-spike (information as a function of the exact time at which a neuron fired), and with population coding (information as a dynamical pattern of firing).
The brain can be investigated from different abstraction levels ranging from the molecular level, neurons, and synapses to networks, maps, systems, and beings.
Networks and emergent behavior: A function can emerge from the joint activation patterns in neural networks. Emergent behavior can- not be observed by studying single entities.
Bottom-up and top-down modeling: In bottom-up brain modeling, large-scale networks are defined using its elementary building blocks. In top-down brain modeling, low-level details are constrained to higher-level observations.
