Information Processing With Population Codes Essay

A series of simple variables will make up for a complex variable. This can either be through the grouping of such simple variables or the more complex combinations and permutations that nature provides. The scholar proposes that there are eleven control systems about human beings and animals and when put in a hierarchical order, they are: intensity, sensation, configuration, transition, event, relationship, category, sequence, program, principle and system concept (Center, 2016).   Despite giving the order, the scholar goes on to say the elements of control systems are autonomous and have absolutely no bearing on each other and this ends up being a major shortcoming of the PTC theory.

Carr does not present his theory on cognition with only his own opinion and reason; he adds many different resources from which he compiled information in support of his argument, including that from many prominent scientists in the field of neuroscience. However, Carr only seems to focus on the fact that technology

After investigating spatial cognition and the construction of cognitive maps in my previous paper, "Where Am I Going? Where Have I Been: Spatial Cognition and Navigation", and growing in my comprehension of the more complex elements of the nervous system, the development of an informed discussion of human perception has become possible. The formation of cognitive maps, which serve as internal representations of the world, are dependent upon the human capacities for vision and visual perception (1). The objects introduced into the field of vision are translated into electrical messages, which activate the neurons of the retina. The resultant retinal message is organized into several forms of sensation and is

Qualities of perseverance, resiliency, and trust encompass the foundation of learning from experiences. A series of intersecting realities, both the trivial and major, encompass the foundation of our lives. In essence, we act as mice running through the maze of life. Researchers at MIT report that an animal’s knowledge from a previous situation can subconsciously influence behavior in new circumstances, shedding light on how our backgrounds inform future choices. When a mouse explores a new maze, neurons fire in its hippocampus, the center of learning and memory. Individual neurons fire in a specific pattern that mimics a mouse’s movement through space. From looking at the patterns and sequences from the firing cells, researchers can determine

Throughout the text, the word ‘neocortex’ is brought up a plentiful amount of times. Over time, the idea of certain items evolves into complex statements that’ll potentially be understood by the reader after they endure the various explanations over a chapter or more. To exemplify this, the term ‘neocortex’ first appears in the introduction; where the basic description of its responsibility to deal with patterns of information(10). Further along, in chapter three, the same term advances into a labyrinth of connections. Not only does this mass, that consists of eighty percent of the human brain, influence memory patterns and such, but that it, “is a comparable hierarchy of pattern recognizers processing actual images of objects...and a hierarchy of concepts… and a hierarchy of thought,”(49). What this means is that our memory is prone to a humans main five senses: smell, sight, hearing, touch, and taste. If one

In addition to studies in species populations, using genetic analysis allows scientists to understand evolutionary patterns in neuroscience, further adding to the body of evidence which proves evolution as fact. Genetic information is inherited from one’s ancestors and as such, determining the relatedness of genetic codes allows biologists to construct a family tree, showing how closely related various members of a family are. Using this logic, a similar method can be used to create an evolutionary tree of life, showing organisms which descended from common ancestors. These trees of life are important because they can be used to show where particular traits begin to appear. Irreducible complexity is an argument from deniers of evolution and

A. attention getter: Your body comprises copious quantities of nervous system cells referred to as neurons. This numerous supply of them can be up to trillions, where about 100 billion inhibit the brain itself. “The number of ways information travels in the human brain is greater than the number of stars in the universe” conveys faculty.washington.edu. Neurons are divergent from other

We describe the results of quantitative information theoretic analyses of neural encoding, particularly in the primate visual, olfactory, taste, hippocampal, and orbitofrontal cortex. Most of the information turns out to be encoded by the firing rates of the neurons that is by the number of spikes in a short time window. This has been shown to be a robust code, for the firing rate representations of different neurons are close to independent for small populations of neurons. Moreover, the information can be read fast from such encoding, in as little as 20 ms. In quantitative information theoretic studies, only a little additional information is available in temporal encoding involving stimulus-dependent synchronization of different neurons,

The brain’s ability to learn, to change in response to experience and to store/retrieve learning through memory it is a fascinating process fundamental to one’s existence. The first scientific study of animal learning demonstrated a form of associative learning - classical conditioning; it can be described as a process of learning where a neutral stimulus (e.g. bell) is paired with an unconditional stimulus (e.g. food) and as a consequence, the neutral stimulus becomes conditioned and comes to elicit the same

The theory further explains that the ability to form a visual image of a word is dependent on whether the word is abstract or concrete. It is generally easier for people to form a visual image of a concrete word and therefore a concrete word is better recalled in an experiment than an abstract word. Research has consistently demonstrated that remembering the word through visualizing it and concrete words, which allow the person to visualize the word easier, are more effective than verbal association and abstract words. One source of evidence for the dual-code theory comes from a series of experiments conducted by Paivio, Smythe and Yuille (1968). In the study the main variable being manipulated was the classification of words as abstract or concrete. They investigated how well student participants recalled paired words that were high-imagery (ex. letter, dress,and juggler) to words that were low-imagery (ex. effort, necessity, and quality). The word lists were combined so that one list contained words that were high-imagery and another list contained words that were low-imagery. There were also lists that combined words that were high and low in imagery. The participants were not given any particular instructions in terms of how to remember the

Research on the processing of visual stimuli have lead to findings that supports the notion of hierarchal modelling in the brain. Hubel and Wiesel (1968) discovered the hierarchal coding of neural cells in the primary visual cortex. Complex cells in this cortex

What this theory leaves unclear is how the brain integrates more than one source of sensory information (i.e. supermodal information) to form a representation of a concept. The brain contains entire areas of cortex that lie between sensory and motor areas that appear to be ‘convergent zones’, that is they bind information from two or more modalities [3,7, 15, 24]. Thereafter, convergent zones then converge onto even higher cortices to form representations [13]. These supermodal areas could help capture the similarities and differences between semantic categories, allowing one to understand the difference between a ‘cat’ and ‘dog’, due to differences in the objects attributes, despite their similarity as pets. Also unclear is if emotion effects the representation of a concept, which

The idea of creating a synthetic consciousness has fascinated the human imagination for many a century. These range from the ancient Pygmalion’s Galatea, the mythological golem, Victorian automatons, to our more recent fancies- computers, robots and other Turing machines. Perhaps the reason for this preoccupation with artificial intelligence is actually a quest to better understand our own consciousness.
