cells, the migration of neuroblasts, and promoting the
generation of new neurons in the hippocampus, therefore
enhancing adult neurogenesis and improving spatial learning
and memory tasks.

Based on the Self-Organization Theory of Dreaming. Wei
Zhang and Benyu Guo. Research Institute of Moral
Education/School of Psychology, Nanjing Normal University,
Nanjing, China The self-organization theory of dreaming
proposes that the sleeping brain is a self-organizing system
that can combine discontinuous and incongruous neuronal
signals (i.e., different elements of dreams) into a relatively
continuous narrative during sleep (Kahn and Hobson, 1993 ;
Kahn et al., 2000 , 2002 ). This theory also implies that
dreams are not independently functional but rather a
coproduct of the sleeping brain, reflecting the dreamer's
physiological and psychological activities such as memory
consolidation, emotion regulation, and reception of external
stimuli (Zhang, 2016 ). By contrast, Freud regarded dreams as
a royal road to the unconscious; dream interpretation has thus
been an important psychoanalytic technique. His theory of
dreams mainly refers to two key points: (a) what are the
materials of a dream? and (b) how do these materials work
together? The answers to these questions are closely related
to an understanding of dream interpretation. In this article,
we refer to the self-organization theory of dreaming and seek
to elucidate its meaning for dream interpretation.

Magdalenian era that in was in total use ( 17 000 cal. BP).
Excavation has revealed habitation structures (sunken
hearths, worked floors, flint and bone fragments forced into
the walls, concretions moved) and numerous tools and
objects in flint, bone and reindeer antler, some being genuine
works of art.

[ 8 ]N,N-dimethyltryptamine compound found in the
hallucinogenic tea ayahuasca, regulates adult neurogenesis in
vitro and in vivo. Jose A. Morales-Garcia, Javier Calleja-

( 2020 ). Abstract: N,N-dimethyltryptamine (DMT) is a
component of the ayahuasca brew traditionally used for ritual
and therapeutic purposes across several South American
countries. Here, we have examined, in vitro and vivo, the
potential neurogenic effect of DMT. Our results demonstrate
that DMT administration activates the main adult neurogenic
niche, the subgranular zone of the dentate gyrus of the
hippocampus, promoting newly generated neurons in the
granular zone. Moreover, these mice performed better,
compared to control non-treated animals, in memory tests,
which suggest a functional relevance for the DMT-induced
new production of neurons in the hippocampus. Interestingly,
the neurogenic effect of DMT appears to involve signaling
via sigma- 1 receptor (S 1 R) activation since S 1 R antagonist
blocked the neurogenic effect. Taken together, our results
demonstrate that DMT treatment activates the subgranular
