In their most common sense, thought and thinking refer to cognitive processes that occur independently of direct sensory stimulation. Core forms include judging, reasoning, conceptformation, problem solving, and deliberation. Other processes, such as entertaining an idea, memory, or imagination, are also frequently considered types of thought.
What is the most fundamental form of thought?
In Tibetan Buddhism, there is the concept of the Three Vajras, or The Three Doors, which are body, speech, and mind.
The human mind can be said to think in the sensory world (sight, sound, taste, touch, smell), to think in recollections of memories from the past (which is still a sensory experience), and to think in the conjured content of the imagination untouched by memory.
These emanations express themselves through the verbal language of speech (which is still a sensory experience of sound; vocal intonations, pitch, rhythm, etc…), and through the non-verbal language of the body (which is still a sensory experience of sight; posture, gestures, eye contact, facial expressions, etc…)
Is thought fundamentally empirical, linguistic, emotional, rational, instinctive, or something else entirely?
For example: When people think in images, are they really rooted in words; or when people speak in words, they are rooted in images.
The mechanisms by which respiratory stimuli induce arousal from sleep and the clinical significance of these arousals have been explored by numerous studies in the last two decades.
Evidence to date suggests that the arousal stimulus in nonrapid eye movement sleep (NREM) is related to the level of inspiratory effort rather than the individual stimuli that contribute to ventilatory drive.
A component of the arousal stimulus proportional to the level of inspiratory effort may originate in mechanoreceptors either in the upper airway or respiratory pump.
Medullary centers responsible for ventilatory drive may also send a signal proportionate to the level of drive to higher centers in the brain which are responsible for arousal.
Thus, the arousal stimulus may consist of multiple components, each increasing as inspiratory effort increases.
The level of effort triggering arousal is an index of the arousability of the brain (arousal threshold).
A deeper stage of sleep, central nervous system depressants, prior sleep fragmentation, and the presence of obstructive sleep apnea (OSA) have been observed to increase the arousal threshold to airway occlusion.
Less information is available concerning the mechanisms of arousal from rapid eye movement (REM) sleep.
While REM sleep is associated with the longest obstructive apneas in patients with OSA, normal human subjects appear to have a similar or lower arousal threshold to respiratory stimuli in REM compared to NREM sleep.
Recent studies have challenged the assumption that the termination of all obstructive apnea is dependent on arousal from sleep.
Improvements in methods to detect and quantitate changes in the cortical electroencephalogram (EEG) may better define the relationship between arousal and apnea termination. This may result in improved criteria for identifying EEG changes of clinical significance.
While little is known concerning the mechanisms of arousal in central sleep apnea, arousal may play an important role in inducing this type of apnea in some patients.

Hypnotherapy is a type of psychological therapy that uses hypnosis to help treat certain mental and physical health conditions. It can also be used to change habits.
Some therapists also use hypnosis to increase the effectiveness of other psychological treatments, or pain management. However, they may describe the treatment they are giving you by its usual name (such as CBT) rather than calling it hypnotherapy.
You can also perform hypnosis on yourself, which is called self-hypnosis.
The unconscious mind is a fully automatic function and, unlike our subconscious mind, is not available for introspection or analysis. This part of our mind is where we hold our initial impressions, base instincts and first experiences, our memories, and the connections we hold between ourselves and the world around us.
Sub conscious
This secondary system regulates everything in our daily lives and is a barrier that our mind puts up to stop us from becoming overwhelmed by the continuous barrage of information through our senses as we interact with the world.
Automates regular habits and removes from conscious mind

The first of these insights involved the types of cues that trigger involuntary memories. Laughland’s recorded observations about what was going on around him as the memories popped into his head revealed that “dynamic” rather than “static” environmental cues are more likely to trigger IAMs.
In other words, new or unexpected details encountered on his trips (e.g. varying weather conditions, or songs on the radio) were far more likely to trigger memories than those details that were always present (e.g. buildings or road signs). This finding highlights the somewhat ironic role that novelty plays in triggering autobiographical memories in our daily lives, with new details in our environment eliciting old memories from our past.
Memory "Chains"
Another interesting finding of the study involved memory “chaining,” in which memories are triggered by a preceding memory rather than by some other internal or external cue. Such memories can often be perceived as new occurrences, but Laughland’s retrospective examination of his audio recordings revealed that many of the IAMs that he perceived to be independent had actually been cued by a prior memory (or memories).
In fact, as many as 23 percent of the IAMs he recorded were chained memories, suggesting that memory chaining is more common than has previously been reported.
IAM "Priming"
Yet another insight provided by the study has to do with the “priming” of IAMs. Very often, an autobiographical memory will unexpectedly pop into our heads, seemingly out of nowhere. Laughland’s review of his audio recordings, however, revealed that many of the spontaneous memories that he recorded during his commutes were not, in fact, spontaneous at all, but had been triggered by cues that he had encountered several seconds or even minutes earlier.
At the moment, the time gap between the cue and the memory it triggered initially prevented him from perceiving a connection between the two events. But the recording revealed that the environmental stimulus had actually “primed” a memory or memories that he recalled later, seemingly out of the blue.
Laughland’s study, and the novel method he employed to gather data, provides evidence that involuntary autobiographical memories are a far more regular occurrence in our daily lives than previous research has suggested. It also gives new insight into how these memories actually occur, indicating that far fewer of them are truly spontaneous than appear to be, getting triggered by cues in our environment rather than simply popping into our heads out of nowhere.
One general point that the study makes clear is what a good opportunity our daily commute offers for experiencing involuntary autobiographical memories. Research on IAMs and related phenomena has shown that “spontaneous thoughts and memories occur more often when people are engaged in undemanding, habitual activities” such as driving.
In other words, when not focused on some task that requires focused attention, our minds tend to wander—and as this study shows, it is very often our autobiographical pasts to which they wander. And if we pay attention to these mind-meanderings during our morning commute, instead of tuning to NPR or cueing up a podcast, we never know where they may take us.
Indeed, given the right environmental cue, they might just lead us back to a cozy little library from our childhood—a brief mental vacation in our distant past to prepare for the busy day in our immediate future.
