Human beings exist in a biological and social system from a micro to a macro level, by means of "collectivity", a dynamic collaboration that they have established together with the elements in that system in a way to complement each other and realize a common goal. Many neuroscientific concepts used today to explain neuronal processes from which mental functions originate are far from searching answers to traditional philosophical questions. However, the brain — as the generator of highly abstract concepts — is so complex that it cannot be explained by minimalistic approaches. The concept of connectome used in recent years to describe neuronal connections from which brain functions originate exemplifies this minimalistic approach, because it only describes structural and functional connections but does not look at brain functions in a holistic view. For this reason, we propose the concept of collectome — to replace the concept of connectome — that describes a homeomorphic and homotopic neuronal framework that has a bicontinuous style of work from micro to macroscale which is based on fractal rules.

This paper is an effort to describe, in neuroscientific terms, one of the most ambiguous concepts of the universe-the soul. Previous efforts to understand what the soul is and where it may exist have accepted the soul as a subjective and individual entity. We will make two additions to this view: (1) The soul is a result of uninhibited mental activity and lacks spatial and temporal information; (2) The soul is an undivided whole and, to become divided, the soul has to be reduced into unconscious and conscious mental events. This reduction process parallels the maturation of the frontal cortex and GABA becoming the main inhibitory neurotransmitter. As examples of uninhibited mental activity, we will discuss the perceptual differences of a newborn, individuals undergoing dissociation, and individuals induced by psychedelic drugs. Then, we will explain the similarities between the structure of the universe and the structure of the brain, and we propose that consideration of the rules of quantum physics is necessary to understand how the soul is reduced into consciousness.

What distinguishes human beings from other living organisms is that a human perceives himself as a 'self'. The self is developed hierarchially in a multi-layered process, which is based on the evolutionary maturation of the nervous system and patterns according to the rules and demands of the external world. Many researchers have attempted to explain the different aspects of the self, as well as the related neural substrates. In this paper, we first review the previously proposed ideas regarding the neurobiology of the self. We then suggest a new hypothesis regarding the hierarchial self, which proposes that the self is developed at three stages: subjective, objective, and reflective selves. In the second part, we attempt to answer the question 'Why do we need a self?' We therefore explain that different parts of the self developed in an effort to identify stability in space, stability against constantly changing objects, and stability against changing cognitions. Finally, we discuss the role of the cerebellum as the neural substrate for the self. [ABSTRACT FROM AUTHOR]
