Roger Wolcott Sperry pioneered the inception of the chemoaffinity hypothesis following his 1960s experiments on the African clawed frog. [2] He would remove the eye of a frog and reinsert it rotated upside-down—the visual nervous system would eventually repair itself, [3] and the frog would exhibit inverted vision.
Jerome Ysroael Lettvin (February 23, 1920 – April 23, 2011), often known as Jerry Lettvin, was an American cognitive scientist, and Professor of Electrical and Bioengineering and Communications Physiology at the Massachusetts Institute of Technology (MIT).
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca
A frog which demonstrates vocalizations in male-male competition is the Lithobates clamitans aka the Green Frog. Typically, they have four types of calls each warning a different level of urgency and each being distinct. The first two calls are types of advertisement calls to establish dominance among the challengers.
Ranoidea platycephala, is a species of frog that is common in most Australian states and territories and is commonly referred to as the water-holding frog but has also been referred to as the eastern water-holding frog, and the common water holding frog. [2]
Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs.Members of this genus are found through much of Eurasia and western North America.
The Mantellidae are an amphibian family of the order Anura (frogs and toads), and are endemic to the Indian Ocean islands of Madagascar and Mayotte. [1] [2] At first glance, the diminutive, brightly-coloured mantellas appear visually similar to (and indeed fill similar ecological niches as) the Latin American poison dart frogs, such as Dendrobates, Oophaga and Phyllobates, among others.
