Orchestrated objective reduction (Orch OR) is a controversial theory postulating that consciousness originates at the quantum level inside neurons (rather than being a product of neural connections). The mechanism is held to be a quantum process called objective reduction that is orchestrated by cellular structures called microtubules.
Sociology of human consciousness uses the theories and methodology of sociology to explain human consciousness. The theory and its models emphasize the importance of language, collective representations, self-conceptions, and self-reflectivity. It argues that the shape and feel of human consciousness is heavily social.
In neuroscience, the critical brain hypothesis states that certain biological neuronal networks work near phase transitions. [ 1 ] [ 2 ] [ 3 ] Experimental recordings from large groups of neurons have shown bursts of activity, so-called neuronal avalanches, with sizes that follow a power law distribution.
The dynamical systems approach to neuroscience is a branch of mathematical biology that utilizes nonlinear dynamics to understand and model the nervous system and its functions. In a dynamical system, all possible states are expressed by a phase space . [ 1 ]
The Dehaene–Changeux model contributed to the study of nonlinearity and self-organized criticality in particular as an explanatory model of the brain's emergent behaviors, including consciousness. Studying the brain's phase-locking and large-scale synchronization, Kitzbichler et al. (2011a) confirmed that criticality is a property of human ...
There are theories proposed of quantum consciousness based on quantum mechanics. [ 7 ] There is an apparent redundancy and parallelism in neural networks so, while activity in one group of neurons may correlate with a percept in one case, a different population may mediate a related percept if the former population is lost or inactivated.
The relative change in ion flow will polarize the membrane based on the properties of the affected ion channel. [1] For example, opening a potassium ion channel in the presynaptic membrane will create a flow of positive potassium ions out of the neuron; loss of the positively charged potassium ions will cause the neuron to become more ...
