Problem-Solving and Spontaneous Tool-Using Ability in European Brown Bears (Ursus arctos arctos) [PDF]
Animal Behavior and Cognition, 2023 Little is known about the cognitive abilities of bears, despite possessing relatively large brains for their body size. One reason this group is perhaps overlooked is because they are thought to fail to conform to the “social brain” hypothesis, by being ...

Frontiers in Neuroanatomy, 2012 Larger mammalian cerebral cortices tend to have increasingly folded surfaces, often considered to result from the lateral expansion of the grey matter (GM), which, in a volume constrained by the cranium, causes mechanical compression that is relieved by ...

Seasonal variation of behavior and brain size in a freshwater fish
Ecology and Evolution, 2021 Teleost fishes occupy a range of ecosystem, and habitat types subject to large seasonal fluctuations. Temperate fishes, in particular, survive large seasonal shifts in temperature, light availability, and access to certain habitats.

Phase dependent modulation of tremor amplitude in essential tremor through thalamic stimulation [PDF]
, 2013 High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition.

, 2019 Amyloid β, Aβ(1–42), is a component of senile plaques present in the brain of Alzheimer’s disease patients and one of the main suspects responsible for pathological consequences of the disease. Herein, we directly visualize the Aβ activity toward a brain-

Journal of Lipid Research, 2000 We have previously presented evidence that most of the 24S-hydroxycholesterol present in the circulation originates from the brain and that most of the elimination of this oxysterol occurs in the liver.

The brain locus of interaction between number and size: A combined functional magnetic resonance imaging and event-related potential study. [PDF]
, 2007 Whether the human brain is equipped with a special neural substrate for numbers, or rather with a common neural substrate for processing of several types of magnitudes, has been the topic of a longstanding debate.

Frontiers in Ecology and Evolution, 2016 The examination of links between a high degree of encephalisation (i.e. large brain mass relative to body size) and the capacity of wildlife to inhabit anthropogenic habitats has formed the basis of several recent studies, although typically they have ...

Phylogenetic variation in cortical layer II immature neuron reservoir of mammals
eLife, 2020 The adult mammalian brain is mainly composed of mature neurons. A limited amount of stem cell-driven neurogenesis persists in postnatal life and is reduced in large-brained species. Another source of immature neurons in adult brains is cortical layer II.

Coordinated evolution of brain size, structure, and eye size in Trinidadian killifish
Ecology and Evolution, 2021 Brain size, brain architecture, and eye size vary extensively in vertebrates. However, the extent to which the evolution of these components is intricately connected remains unclear.
