Factors that affect on the sexual behavior of leeches not only in nature, but also in artificial conditions remain largely unexplored. We did not find data on the behavior of medicinal leeches, which are not placed in time from the aquatic environment in the peat-soil conditions after the appearance of clitella on their bodies.

Hirudo Medicinalis and the plastic surgeon
Journal of Plastic, Reconstructive and Aesthetic Surgery, 2004Medicinal leech therapy is an ancient craft that dates back to ancient Egypt and the beginnings of civilisation. The popularity of Hirudo Medicinalis has varied throughout history, reaching such a peak in Europe in the early 19th century that supplies were exhausted.

Biogenic monoamines in Hirudo medicinalis
Histochemie, 1968The distribution of certain catecholamines and indoleamines in the ventral nerve cord and the body segments of the medical leech, Hirudo medicinalis, was studied with the fluorescence microscope technique of Falck and Hillarp, with microspectrofluorometry, and with chemical determinations of the amines. The six cells of the segmental ganglia previously

Nonassociative learning in the leech Hirudo medicinalis
Behavioural Brain Research, 2001In the present study we examined nonassociative learning of the induction of swimming which was evoked by weak electrical stimulation in the leech Hirudo medicinalis. The behavioural response to stimuli applied repeatedly to the body wall at an inter-trial interval (ITI) of 1 min decreased, eventually ceased, and then recovered spontaneously.

A silicon model of the Hirudo swim oscillator
IEEE Engineering in Medicine and Biology Magazine, 2000Discusses using VLSI-based technology for recreating living neuronal circuits. The authors describe a study in which one subunit of the oscillatory network of the leech Hirudo medicinalis was reconstructed on a cell-by-cell, synapse-by-synapse basis using dedicated IC-based neural elements.

Science, 1996
In August 1994, Ken Muller, chair of the neuroscience program at the University of Miami Medical School, asked if I would compose a musical tribute ([1][1]) to neuroscientist John G. Nicholls ([2][2], [3][3]) for his 65th birthday, as I am a scientist ([4][4]), a composer, and a former student ...

The Hirudo medicinalis species complex
Naturwissenschaften, 2012Recently, Hildebrandt and Lemke (Naturwissenschaften 98:995-1008, 2011) argued that the taxonomic status of the three European medicinal leeches, Hirudo medicinalis Linnaeus 1758, Hirudo verbana Carena 1820, and Hirudo orientalis Utevsky and Trontelj (Parasitol Res 98:61-66, 2005) is "questionable" since "all three species interbreed in the laboratory".

Von den etwa 300 Egelarten, die es auf der Erde gibt, leben die meisten in Süßwasser. Je nach Größe, Anzahl und Bissstelle können sie für Fische und Amphibien, für badende Tiere oder Menschen unterschiedlich gefährlich sein. Umgekehrt hat sich der Mensch einige wenige Arten dieser Parasiten für medizinische Zwecke zunutze gemacht.

The aim of the work is to obtain optimal artificial conditions for the maintenance and breeding of medicinal leeches of the species Hirudo verbana and Hirudo orientalis. 180 medicinal leeches were used in the study: 100 leeches of the H. verbana species and 80 H. orientalis leeches.

Hormonal control of spermatogenesis in Hirudo medicinalis
General and Comparative Endocrinology, 1967Neurosecretion in the brain of annelids has attracted considerable attention since its first recognition in the supraesophageal ganglion of Nereis by Berta Scharrer in 1936; in the polychetes and oligochetes it has been implicated in the control of reproduction, amongst other functions (see Bern and Hagadorn, 1965 for references). In the Hirudinea, the
