A comparative analysis of the dopaminergic innervation of the executive caudal nidopallium in pigeon, chicken, zebra finch, and carrion crow

This study describes the trajectory of the nidopallium caudolaterale in pigeon, chicken, carrion crow and zebra finch, and shows that comparable to the PFC in mammals, the NCL in birds varies considerably across species.

“Dendroarchitectonics”: From Santiago Ramón y Cajal to Enrique Ramón-Moliner or vice versa?

The morphological taxonomy of neurons proposed by Enrique Ramón-Moliner in the vertebrate central nervous system based on "dendroarchitectonics" and compare these findings with Santiago Ramón y Cajal's work corroborate the rejection of the interpretative framework of ontogeny as a simple, speedy repetition of the phylogeny.

It is proposed that the dynamics of the dopamine system constitute the main neural basis underlying the situational variability of stuttering, in particular the mechanisms related to motor learning and the execution of movement sequences.

It is suggested that episodic memory and its associated memory systems of sensory, working, and semantic memory as a whole ought to be considered together as the conscious memory system in that they give rise to the phenomenon of consciousness.

As soon as there was life, there was danger: the deep history of survival behaviours and the shallower history of consciousness

It is argued that fear is a universal innate emotion that the authors humans have inherited from their mammalian ancestors by virtue of having inherited conserved features of their nervous systems, but is, instead, a defensive survival circuit that detects threats, and in response, initiates defensive survival behaviours and supporting physiological adjustments.

Two Types of Withdraw-to-Eat Movement Related to Food Size in Long-Tailed Macaques (Macaca fascicularis): Insights into the Evolution of the Visual Control of Hand Shaping in Anthropoid Primates

The present study finds that Balinese long-tailed macaques (Macaca fascicularis), video recorded while spontaneously eating at the Sacred Monkey Forest Sanctuary in Ubud in Indonesia, displayed two types of hand movements associated with twotypes of withdraw movements to place food items in the mouth.

The Challenging Pathway of Treatment for Neurogenesis Impairment in Down Syndrome: Achievements and Perspectives

Prospects and challenges for fetal therapy in individuals with DS are discussed as a potential means of drastically counteracting the deleterious effects of gene triplication.

This work considers what is known about the organization of the neocortex in species with the least expanded neocortex from 6 major clades of the mammalian radiation.

Homology, neocortex, and the evolution of developmental mechanisms

A principle of brain evolution is suggested: that natural selection preferentially preserves the integrity of information-processing pathways, whereas other levels of biological organization, such as the three-dimensional architectures of neuronal assemblies, are less constrained.

Evolution and Development of the Mammalian Cerebral Cortex

The neocortical organization in early mammals is demonstrated, which helps to elucidate how the large, complex human brain evolved from a long line of ancestors.

The evolution and functions of nuclei of the visual pulvinar in primates

In this review, the history of current understanding of the organization of the pulvinar complex of mammals is outlined, including more recent evidence from studies of both New and Old World monkeys, prosimian galagos, and close relatives of primates.

Hominins and the emergence of the modern human brain.

Architectonic features and relative locations of primary sensory and related areas of neocortex in mouse lemurs

The laminar organization of V1 further supports the view that subl layers of layer 3 of primates have been commonly misidentified as sublayers of layer 4, and can usefully guide future studies of cortical connectivity and function.

The evolution of parietal cortex in primates.

The basic uniformity in structure of the neocortex.

It is suggested that the intrinsic structure of the neocortex is basically more uniform than has been thought and that differences in cytoarchitecture and function reflect differences in connections.

Neocortical Lamination: Insights from Neuron Types and Evolutionary Precursors

Evidence is summarized suggesting the hypothesis that the developmental program of three-layer olfactory cortex was co-opted to form six-layer mammalian neocortex, elaborating IT cortical units in layers 2–6 while adding layer 4 stellate cells, layer 5B pyramidal tract (PT) cells and layer 6 corticothalamic (CT) cells.

Neuron densities vary across and within cortical areas in primates

Cortex architecture varies greatly within and across primate species, but cell density is greater in cortex devoted to the early stages of sensory processing in the Old World macaque and baboon.
