Using functional connectivity approaches to study resting-state fMRI data in a group of habitual coffee drinkers, we herein show that coffee consumption decreased connectivity of the posterior default mode network (DMN) and between the somatosensory/motor networks and the prefrontal cortex, while the connectivity in nodes of the higher visual and the right executive control network (RECN) is increased after drinking coffee; data also show that caffeine intake only replicated the impact of coffee on the posterior DMN, thus disentangling the neurochemical effects of caffeine from the experience of having a coffee. Herein, we aim to explore the resting-state fMRI data in a group of habitual coffee drinkers before and after acute coffee consumption, using network functional connectivity approaches. This is significant in that Ca 2+-permeable AMPA receptors are casually related to ischemia-induced neuronal death [ 12]. In aging neurons, REST affords neuroprotection by suppressing genes involved in apoptosis and oxidative stress including many Bcl2 family members [ 11•].
Neural restrictive silencer factor recruits mSin3 and histone deacetylase complex to repress neuron-specific target genes. This is significant in that GluN2B expression restricts synaptic incorporation of AMPARs, reduces the threshold for and enhances the magnitude of LTP, and promotes hippocampal- dependent learning, plasticity-induced spine growth and dendritic patterning critical to information processing [ 45]. In terms of sleep hours I didn’t notice any improvement the first 3 nights and I was still waking at 4ish.

In addition, the subset of transcriptionally responsive genes identified by unbiased, genome-wide studies involving REST chromatin immunoprecipitation and deep sequencing (ChIP-seq) in a neuroblastoma cell line [ 49] differs from that identified by large-scale ChIP-seq in Jurkat cells [ 48] and by ChIP-on-chip in mouse neural stem cells [ 50]. Using large-scale transcriptome arrays, Baram and colleagues [ 20] found that only a small subset (~10%) of putative REST targets are silenced by REST in response to seizures despite the fact that REST is increased several-fold.REST directly binds the short splice variant of TET3 (the predominant isoform found in neurons) and directs it to the promoters of REST target genes, where TET3 promotes conversion of methyl cytosine to 5-hyodroxy methylcytosine, resulting in context-specific gene transcription [ 42]. Interestingly, the switch can be disrupted by brief bouts of adverse experience in the form of maternal deprivation, indicating that the synaptic NMDAR phenotype can be regulated by REST-dependent epigenetic remodeling [ 10]. From the neurobiological perspective, both caffeine and chlorogenic acids have well-documented psychoactive actions, whereas caffeine is mostly an antagonist of the main adenosine receptors in the brain—A 1 and A 2A receptors, leading to the disinhibition of excitatory neurotransmitter release and enhancement of dopamine transmission via D2 receptors ( Fredholm et al. Just to check, did you mean to say “If I don’t get drowsy or sleepy…” I can’t work out if you mean you take them when you don’t feel sleepy, or if they help you sleep without making you drowsy?
