Abstract:

The brain has been one of the central foci in studies of vertebrate evolution. Work in East African cichlids and other emerging fish models like the Mexican cavefish (Astyanax mexicanus) offer new insight on the role of patterning on brain evolution. These fish can be grouped into two major categories according to habitat; for cichlids it is rock-dwelling (known locally as mbuna) and sand-dwelling (non-mbuna) lineage. The brain development of mbuna versus non-mbuna is defined by changes in gene deployment working along the dorsal/ventral (DV) and anterior/posterior (AP) neuraxes, respectively.

Abstract:

<p>Here I look at three stages in the evolutionary development of mammalian brains. Chapter one addresses how connectivity in neocortex scales with brain size. This is of evolutionary interest because it helps define the basic mammalian condition. Neocortical white matter increases disproportionately in large brains. This might reflect increases in the number of connections per neuron. It might also reflect scaling in axon diameter. I compare these hypotheses by examining white matter-gray matter scaling in cerebellum. Because the white matter of cerebellum lacks cortico-cortical connections,

Abstract:

A major focus of evolutionary neurobiology has been on whether different regions of the eutherian brain evolve in concert, and how free the brain is to evolve independently of body plans. Since the eutherian brain is loosely modularized, such that one region is rarely isolated for specialization at the expense of others, but the design of modularization itself can be adapted by tweaking developmental programs, the degree to which brain regions must evolve in concert and can evolve independently may carry a deep phylogenetic signal.

Brain size varies greatly among vertebrates. It has been proposed that the diversity of brain size is produced and maintained through a balance of adaptations to different types and levels of cognitive ability and constraints for adaptive evolution. Phylogenetic comparative studies have made major contributions to our understanding of brain size evolution. However, previous studies have nearly exclusively focused on mammalian and avian taxa and almost no attempts have been made to investigate brain size evolution in ectothermic vertebrates.

Although the human brain has been studied over past decades at morphological and histological levels, much remains unknown about its molecular and genetic mechanisms.

Nevertheless, such drastic changes in the human brain may have arisen not only through morphological changes but also through changes in the expression levels of genes and transcripts.

In doing so, it makes predictions about the relationships between brain size, adaptive knowledge, group size, social learning, and the length of the juvenile period.

Background: Long considered to be the building block of life, it is now apparent that protein is only one of many functional products generated by the eukaryotic genome.

Nevertheless, the biological function of the vast majority of eutherian long intergenic noncoding RNAs (lincRNAs) has not been experimentally validate

The metabolic expense of producing and operating neural tissue required for adaptive behaviour is considered a significant selective force in brain evolution. In primates, brain size correlates positively with group size, presumably owing to the greater cognitive demands of complex social relationships in large societies. Social complexity in eusocial insects is also associated with large groups, as well as collective intelligence and division of labour among sterile workers. However, superorganism phenotypes may lower cognitive demands on behaviourally specialized workers resulting in selecti

Abstract:

Here I search for the potential relationship between behavioural flexibility and brains in cephalopods, within and between species, foIIowing the behavioural drive (Wyles et al., 1983). At the intra-specific level (Octopus vulgaris), I evaluated whether differences in performance between individuals reflected differences in body and brain size and the effect of other intervening factors (e.g. sex, site of capture). In order to do so, a battery of eight consecutive experiments (spamling over 12 days) was presented to a total of 55 naIve octopuses (other 46 animals figured as controls). I utiliz

Abstract:

Maintaining the appropriate transcriptional balance in the cell is a complex process involving numerous mechanisms, including the action of transcription factors and non-coding regulatory elements. Such processes are key to maintaining healthy central nervous system (CNS) functioning, and can be modulated through the interaction of both genes and environment in a ‘G x E’ mechanism. If the regulation of a certain gene or gene set is altered inappropriately in the brain, this can result in neuronal dysfunction which may contribute to psychiatric or CNS conditions. This thesis primarily aimed to

Abstract:

Gyrencephaly (the folding of the surface of the neocortex) is a mammalian-specific trait present in almost all mammalian orders. Despite the widespread appearance of the trait, little is known about the mechanism of its genesis or its adaptive significance. Still, most of the hypotheses proposed concentrated on the pattern of connectivity of mature neurons as main components of gyri formation. Recent work on embryonic neurogenesis in several species of mammals revealed different progenitor and stem cells and their neurogenic potential as having important roles in the process of gyrification.

Abstract:

The database on hand preferences in non-human primates provides inconsistent and inconclusive findings, and is plagued by gaps and methodological issues. I studied hand preferences in the bonobo, which is a very interesting model for investigating evolutionary hypotheses on human handedness. There are few previous data on bonobos and they are from small samples and for relatively simple tasks. I studied a large sample of 94 bonobos in three zoos and one sanctuary, on a variety of actions. Five studies were performed to record: 1. hand use for spontaneous daily actions (non-social). 2. hand use
