Propositional and predicate calculus serve to express many complex kinds of knowledge, and many inferences can be understood in terms of logical deduction with inferences rules such as modus ponens.
Valua Vitaly Advertisement For centuries people have pondered the meaning of dreams. Early civilizations thought of dreams as a medium between our earthly world and that of the gods.
In fact, the Greeks and Romans were convinced that dreams had certain prophetic powers. Carl Jung who studied under Freud also believed that dreams had psychological importance, but proposed different theories about their meaning.
Since then, technological advancements have allowed for the development of other theories. Humans, the theory goes, construct dream stories after they wake up, in a natural attempt to make sense of it all.
Yet, given the vast documentation of realistic aspects to human dreaming as well as indirect experimental evidence that other mammals such as cats also dream, evolutionary psychologists have theorized that dreaming really does serve a purpose. So, over the years, numerous theories have been put forth in an attempt to illuminate the mystery behind human dreams, but, until recently, strong tangible evidence has remained largely elusive.
Yet, new research published in the Journal of Neuroscience provides compelling insights into the mechanisms that underlie dreaming and the strong relationship our dreams have with our memories. Cristina Marzano and her colleagues at the University of Rome have succeeded, for the first time, in explaining how humans remember their dreams.
The scientists predicted the likelihood of successful dream recall based on a signature pattern of brain waves. In order to do this, the Italian research team invited 65 students to spend two consecutive nights in their research laboratory. During the first night, the students were left to sleep, allowing them to get used to the sound-proofed and temperature-controlled rooms.
Our brain experiences four types of electrical brain waves: There are five stages of sleep; most dreaming and our most intense dreams occur during the REM stage.
The students were woken at various times and asked to fill out a diary detailing whether or not they dreamt, how often they dreamt and whether they could remember the content of their dreams. While previous studies have already indicated that people are more likely to remember their dreams when woken directly after REM sleep, the current study explains why.
Those participants who exhibited more low frequency theta waves in the frontal lobes were also more likely to remember their dreams. This finding is interesting because the increased frontal theta activity the researchers observed looks just like the successful encoding and retrieval of autobiographical memories seen while we are awake.
That is, it is the same electrical oscillations in the frontal cortex that make the recollection of episodic memories e. Thus, these findings suggest that the neurophysiological mechanisms that we employ while dreaming and recalling dreams are the same as when we construct and retrieve memories while we are awake.
In another recent study conducted by the same research team, the authors used the latest MRI techniques to investigate the relation between dreaming and the role of deep-brain structures.
In their study, the researchers found that vivid, bizarre and emotionally intense dreams the dreams that people usually remember are linked to parts of the amygdala and hippocampus. While the amygdala plays a primary role in the processing and memory of emotional reactions, the hippocampus has been implicated in important memory functions, such as the consolidation of information from short-term to long-term memory.existence has the purpose of characterizing unseen right- and wrong-ethical values, could when it is at its best, human life.
