This model is the Integrate-and-Fire (IF) model that was mentioned in Section 2.3. Closely related to IF model is a model called Spike Response Model (SRM) (Gerstner, W. (1995) [15] Pages 738-758) that is dependent on impulse function response convoluted with the input stimulus signal. This forms a base for a large number of models developed ...
Raichle coined the term "default mode" in 2001 to describe resting state brain function; [19] the concept rapidly became a central theme in neuroscience. [20] Around this time the idea was developed that this network of brain areas is involved in internally directed thoughts and is suspended during specific goal-directed behaviors.
Discussion on the brain's criticality have been done since 1950, with the paper on the imitation game for a Turing test. [9] In 1995, Andreas V. Herz and John Hopfield noted that self-organized criticality (SOC) models for earthquakes were mathematically equivalent to networks of integrate-and-fire neurons, and speculated that perhaps SOC would occur in the brain. [10]
The model is derived from the architecture of the brain and nervous system. Systems 3-2-1 are identified with the ancient brain or autonomic nervous system. System 4 embodies cognition and conversation. System 5, the higher brain functions, include introspection and decision making. [6]
It consists of 2.5 million simulated neurons organized into subsystems that resemble specific brain regions, such as the prefrontal cortex, basal ganglia, and thalamus. It can recognize numbers, remember them, figure out numeric sequences, and even write them down with a robotic arm. [2] [3] It is implemented using Nengo.
The triune brain model argues that these structures are relatively independent from one another, but that they are still connected to each other in some form or another. [1] The model views different cognitive behaviors as caused by three different entities instead of one.
Siegel's model of the brain attempts to simplify the complexity of brain formation in emphasizing interaction between the brainstem, limbic systems (hippocampus and amygdala) and middle prefrontal cortex. Close proximity between the Limbic System (Hippocampus & Amygdala) and Brainstem. Brainstem: A major role of the brainstem involves regulation.
Goodale and Milner [2] amassed an array of anatomical, neuropsychological, electrophysiological, and behavioural evidence for their model. According to their data, the ventral 'perceptual' stream computes a detailed map of the world from visual input, which can then be used for cognitive operations, and the dorsal 'action' stream transforms incoming visual information to the requisite ...
