The Big Brain Theory is an American television show on the Discovery Channel that first aired in 2013, hosted by Kal Penn. [2] Eight episodes were produced. [3]
Friston makes the following claims about the explanatory power of the theory: "This model of brain function can explain a wide range of anatomical and physiological aspects of brain systems; for example, the hierarchical deployment of cortical areas, recurrent architectures using forward and backward connections and functional asymmetries in ...
According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. Predictive coding is member of a wider set of theories that follow the Bayesian brain hypothesis .
In 2013, Stroup appeared in the first season of Discovery Channel's reality TV series The Big Brain Theory: Pure Genius, [12] an engineering competition consisting of 10 contestants from across the country, which aired from May to June 2013. Each week contestants were put to the test, competing against each other in two teams to design, build ...
The Boltzmann brain thought experiment suggests that it might be more likely for a brain to spontaneously form in space, complete with a memory of having existed in our universe, rather than for the entire universe to come about in the manner cosmologists think it actually did.
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Many of the methods and techniques central to neuroscientific discovery rely on assumptions that can limit the interpretation of the data. Philosophers of neuroscience have discussed such assumptions in the use of functional magnetic resonance imaging (fMRI), [6] [7] dissociation in cognitive neuropsychology, [8] [9] single unit recording, [10] and computational neuroscience.

The brain must obtain a large quantity of information based on a relatively short neural response. Additionally, if low firing rates on the order of ten spikes per second must be distinguished from arbitrarily close rate coding for different stimuli, then a neuron trying to discriminate these two stimuli may need to wait for a second or more to ...
