Many animals produce continuous brainwaves, known as the electroencephalogram (EEG), but it is not known at what point in evolution the EEG developed. Planarians possess the most primitive form of brain, but still exhibit learning and memory behaviors. Here, we observed and characterized the EEG waveform of the planarian. We inserted a monopole electrode into the head of a planarian on a cold stage, and were able to observe the EEG at sub-microvolt amplitudes. The EEG had a continuous waveform… Expand
Photo-stimulation effect on the human EEG alpha-wave spectrum
The EEG α wave mode shows chaotic characters and the frequency spectrum is entrained to the external photo-stimulation peak. This effect was observed exceedingly in the photo-sensitive children asExpand
Desarrollo de una interfaz gráfica para el análisis no-lineal de series de tiempo: electroencefalogramas
Objective: We developed a graphical interface for the group of routines in the package executable TISEAN (Time Series Analysis) which allows the study of the behavior of time series (TS) associatedExpand
Galantamine reverses scopolamine-induced behavioral alterations in Dugesia tigrina
TLDR
The results demonstrate, for the first time in planaria, scopolamine’s effects in causing learning and memory impairments and galantamine”s ability in reversing scopolamines-induced memory impairment. Expand
An automated training paradigm reveals long-term memory in planarians and its persistence through head regeneration
TLDR
It is shown that worms exhibit environmental familiarization, and that this memory persists for at least 14 days – long enough for the brain to regenerate, and it is proposed that trained, decapitated planarians exhibit evidence of memory retrieval in a savings paradigm after regenerating a new head.

Carbamazepine inhibits distinct chemoconvulsant-induced seizure-like activity in Dugesia tigrina
TLDR
The results demonstrate, for the first time, the anti-seizure pharmacology of carbamazepine and oxcarbazepine in an invertebrate seizure model. Expand
Effect of Donepezil, Tacrine, Galantamine and Rivastigmine on Acetylcholinesterase Inhibition in Dugesia tigrina
TLDR
The results showed for the first time the anticholinesterasic and convulsant effect, in addition to the decrease in locomotion induced by those drugs in a model of invertebrates, in order to propose a model for an in vivo screening of substances with inhibitory activity of the enzyme acetylchlinesterase.

Planarian regeneration in space: Persistent anatomical, behavioral, and bacteriological changes induced by space travel
Abstract Regeneration is regulated not only by chemical signals but also by physical processes, such as bioelectric gradients. How these may change in the absence of the normal gravitational andExpand
Vertically- and horizontally-transmitted memories – the fading boundaries between regeneration and inheritance in planaria
TLDR
This hypothesis paper re-evaluate canonical ideas about the interaction between developmental, genetic and evolutionary processes through the lens of planaria, an invertebrate model organism which challenges fundamental assumptions regarding reproduction. Expand
Physiological controls of large‐scale patterning in planarian regeneration: a molecular and computational perspective on growth and form
TLDR
This work overviews the multi‐scale problem of understanding pattern regulation in planaria, with specific focus on bioelectric signaling via ion channels and gap junctions (electrical synapses), and computational efforts to extract explanatory models from functional and molecular data on regeneration.

Drug delivery and epimorphic salamander‐type mouse regeneration: A full parts and labor plan
TLDR
The discovery of the MRL mouse and the elucidation of the underlying molecular pathway centering around hypoxia inducible factor, HIF‐1&agr;, has allowed a drug and materials approach to regeneration in mice and hopefully humans. Expand

TLDR
The optic ganglion of Dytiscus is re-examined in the hope that the results would show what might be expected of nerve cells in general and suggest an explanation for some of the reactions of the cerebral cortex. Expand

TLDR
The planarian is the simplest living animal having a body plan of bilateral symmetry and cephalization and an extraordinary plasticity and regenerative capacity, and sensitivity to neurotoxins, provide unique opportunities for studying the reorganization of the nervous system after injury. Expand

Structure of the Planarian Central Nervous System (CNS) Revealed by Neuronal Cell Markers
TLDR
The gross structure of the planarian CNS along the anterior-posterior (A–P) axis is strikingly similar to the distribution pattern of the “primary” neurons of vertebrate embryos which differentiate at the neural plate stage to provide a fundamental nervous system, although the vertebrate CNS is located on the dorsal side.

A phototaxis assay system is devised to analyze light response recovery during head regeneration and determined that light evasion is markedly re-established 5 days after amputation, suggesting that 1020HH and eye53 may be involved in the functional recovery and maintenance of the visual system.
