Túngara Frog
The Túngara frog (''Engystomops pustulosus'') is a species of frog in the family Leptodactylidae. It is a small nocturnal terrestrial frog found in Mexico, Central America, and the northeastern regions of South America. The tungara frog exhibits interesting behavior between the sexes, in both male/male and male/female interactions. Male vocalizations are critical in female mate choice, and females often prefer males who give complex mating calls at a lower frequency rather than simple calls at a higher frequency. This long distance vocalization is the primary mating behavior of tungara frogs, and it is produced by a fibrous mass in the frog’s larynx. The tungara frog may also have a mutualistic relationship with tarantulas, where tarantulas participate in predator defense while frogs protect tarantula eggs. Tungara frogs have distinct coloration which helps defend them from predators Description ''Engystomops pustulosus'' is a small species of terrestrial frog growing to a ...

American Green Tree Frog
The American green tree frog (''Dryophytes cinereus'' or ''Hyla cinerea'') is a common arboreal species of New World tree frog belonging to the family Hylidae. This nocturnal insectivore is moderately sized and has a bright green to reddish-brown coloration. Commonly found in the central and southeastern United States, the frog lives in open canopy forests and permanent waters with abundant vegetation. When defending territory, the frog either emits aggressive call signals or grapples with intruders. To avoid predation, the frog hides in its aquatic habitat. Females are larger than males and breed through amplexus. In contrast, males emit low frequency advertisement calls to attract females. During mating competition, males will eavesdrop on neighboring rivals and either adjust their signal timing or remain silent to intercept call signals and mate with approaching females. Androgens energize males to vocalize. Description Many individuals of the American green tree frog are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricket Frog
Cricket frogs, genus ''Acris'', are small, North American frogs of the family Hylidae. They occur in northern Mexico ( Coahuila), the United States east of the Rocky Mountains, and in southern Ontario, Canada. They are more aquatic than other members of the family, and are generally associated with permanent bodies of water with surface vegetation. This is a quite important aspect of their survival, as adult cricket frogs suffer high mortality rates when submerged in poorly oxygenated water (typically less than 24 hours on average in water that is ~1.2 mg/L). The common and scientific names refer to their call, which resembles that of a cricket. The two common species are ''A. crepitans'' and ''A. gryllus''. ''A. crepitans'' are found in mesic woodlands as well as xeric grasslands, whereas ''A. gryllus'' are concentrated in mesic woodlands. Cricket frogs are able to communicate and attract each other using a specific frequency of their mating call, that sounds like a cricket ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurophysiology
Neurophysiology is a branch of physiology and neuroscience that studies nervous system function rather than nervous system architecture. This area aids in the diagnosis and monitoring of neurological diseases. Historically, it has been dominated by electrophysiology—the electrical recording of neural activity ranging from the molar (the electroencephalogram, EEG) to the cellular (intracellular recording of the properties of single neurons), such as patch clamp, voltage clamp, extracellular single-unit recording and recording of local field potentials. However, since the neurone is an electrochemical machine, it is difficult to isolate electrical events from the metabolic and molecular processes that cause them. Thus, neurophysiologists currently utilise tools from chemistry (calcium imaging), physics (functional magnetic resonance imaging, Functional magnetic resonance imaging, fMRI), and molecular biology (site directed mutations) to examine brain activity. The word originates f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroendocrinology
Neuroendocrinology is the branch of biology (specifically of physiology) which studies the interaction between the nervous system and the endocrine system; i.e. how the brain regulates the hormonal activity in the body. The nervous and endocrine systems often act together in a process called neuroendocrine integration, to regulate the physiological processes of the human body. Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus, controls secretion of pituitary gland hormones, and has subsequently expanded to investigate numerous interconnections of the endocrine and nervous systems. The endocrine system consists of numerous glands throughout the body that produce and secrete hormones of diverse chemical structure, including peptides, steroids, and neuroamines. Collectively, hormones regulate many physiological processes. The neuroendocrine system is the mechanism by which the hypothalamus maintains homeostasis, regulating reproduction, metab ...

Neuroanatomy
Neuroanatomy is the study of the structure and organization of the nervous system. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord (together called the central nervous system, or CNS) and the routes of the nerves that connect to the rest of the body (known as the peripheral nervous system, or PNS). The delineation of distinct structures and regions of the nervous system has been critical in investigating how it works. For example, much of what neuroscientists have learned comes from observing how damage or "lesions" to specific brain areas affects behavior or other neural functions. For information about the composition of non-human animal nervous systems, see nervous system. For information ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sociogenomics
Sociogenomics, also known as social genomics, is the field of research that examines why and how different social factors and processes (e.g., social stress, conflict, isolation, attachment, etc.) affect the activity of the genome. Social genomics as a field is very young (< 20 years old) and was spurred by the scientific understanding that the expression of genes to their gene products, though not the DNA sequence itself, is affected by the external environment. Social genomics researchers have thus examined the role of social factors (e.g. isolation, rejection) on the expression of individual genes, or more commonly, clusters of many genes (i.e. gene profiles, or gene programs). History In the early 2000s, initial work on this topic was conducted in animal model systems, such as , |
