An investigation of the differential brain structures can be conducted by clinico-anatomical correlations. Here, the mechanisms associated with REM sleep are removed to observe whether there is a cessation in dreaming as well, then the areas thought to be associated with dreaming are removed to see if REM sleep is also made impossible. [6]
Dreaming is a state of the brain that is similar to yet different from the waking consciousness, and interaction and correlation between the two is necessary for optimal performance from both. One study conducted measuring brain activity via EEG used Hobson's AIM model to show that quantitatively dream consciousness is remarkably similar to ...
Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate with a specific experience. [ 3 ] [ 4 ] The set should be minimal because, under the materialist assumption that the brain is sufficient to give rise to any given conscious experience ...
One explanation for this correlation is that the PGO electrical waves, which precede the eye movements, also influence memory. [17] REM sleep could provide a unique opportunity for "unlearning" to occur in the basic neural networks involved in homeostasis, which are protected from this "synaptic downscaling" effect during deep sleep. [30]: 89
This close correlation of REM sleep and dream experience was the basis of the first series of reports describing the nature of dreaming: that it is a regular nightly occurrence, rather than an occasional phenomenon, and that it is a high-frequency activity within each sleep period occurring at predictable intervals of approximately every 60 ...
Experiments and studies have been taken out to test neural correlations of lucid dreams with consciousness in dream research. Although there are many difficulties in conducting lucid dreaming research (e.g. number of lucid subjects, 'type' of lucidity achieved, etc.), there have been studies with significant results.
Let denote the spatio-temporal stimulus vector preceding the 'th time bin, and the spike count in that bin. The stimuli can be assumed to have zero mean (i.e., [] =).If not, it can be transformed to have zero-mean by subtracting the mean stimulus from each vector.
Implicit about the decoding hypothesis is the assumption that neural spiking in the brain somehow represents stimuli in the external world. The decoding of neural data would be impossible if the neurons were firing randomly: nothing would be represented. This process of decoding neural data forms a loop with neural encoding. First, the organism ...
