eGABA A Rs may also be the preferential high-affinity tar-get of the naturally occurring GABA precursor γ-hydroxybutyric acid (GHB), adepressant drug that is also used recreationally. However, this observation remainscontroversial since the α4β1δ subunit combination expressed in Xenopus oocytes inthis study are believed to exist only in very low numbers, if at all, in the mammalianbrain
Test on a4b2d receptors rather than a4b1d that they used

by far the most illuminating to me is the idea that mental causation works from virtual futures towards the past 00:33:17 whereas physical causation works from the past towards the future and these two streams of causation sort of overlap in the present
for - comparison - mental vs physical causation - adjacency - Michael Levin's definition of intelligence - Sheldrake's mental vs physical causation
key insight - comparison - mental vs physical causation - mental causation works from virtual futures to past - physical causation works from past to future - this is an interesting way of seeing things
adjacency - between - direction of mental vs physical causation - Michael Levin's definition of intelligence (adopting WIlliam James's idea) and cognition and cognitive light cones of living organisms:: - having a goal - having autonomy and agency to reach that goal - adjacency statement - Levin adopts a definition of cognition from scientific predecessors that relate to goal activity. - When an organism chooses one specific behavioral trajectory over all other possible ones in order to reach a goal - this is none other than choosing a virtual future that projects back to the present - In our species, innovation and design is based on this future-to-present backwards projection

sumption of decreasing virulence with time is a double-edged sword in NativeAmerican disease history. Recent Native Americans have extreme susceptibility to oftenacute infections such as influenza and tuberculosis (Indian Health Service 1999; Koenig1921; Matthews 1886). Although, as detailed later in this paper, many factors, includingsocio-economic conditions, diet, and other concurrent infections, could be contributing tothis incidence, these factors seem to pale by comparison with disease history. Essentially,current incidence rates account for the absence of crowd infections prior to Columbus andabsence explains the present incidence rate
