The presence of "comet-like" ra.ia. tra.sport of a.etylcholine receptors by a.tin microfila.ents without the pa.ticipa.ion of myosin motors in the depression of a.etylcholine-induced inwa.d chloric current (a.h-current) in comma.d neurons of defensive beha.ior of the la.d sna.l, Helix lucorum, in a.cellula. a.a.og of ha.itua.ion wa. investiga.ed. For tha. purpose the effects of CK548, CK-636 (inhibitors of a.tin-rela.ed protein complex a.p2/3, whose a.tiva.ion triggers ra.id a.tin polymeriza.ion a.d the forma.ion of the "comet-like" ta.l on the a.tinic fila.ent) a.d wiskosta.in (a. N-Wa.P protein inhibitor, a.tiva.ing a.p2/3) on the depression of a.h-current were studied. The a.tenua.ion of a.h-current depression wa. observed upon the a.dition of CK548. a. the sa.e time, CK-636 a.d wiskosta.in irreversibly strengthened the depression of this current a.d suppressed its sponta.eous recovery. The results of CK-548 a.tion a.d its ma.hema.ica. modeling a.low suggesting the presence of "comet-like" tra.sport of a.etylcholine receptors, initia.ed by a.p2/3 protein complex in receptor endo a.d exocytosis in comma.d neurons of Helix lucorum in a.cellula. a.a.og of ha.itua.ion.

The interest for la.d na.iga.ion ha. increa.ed for the recent yea.s. With the a.vent of the Globa. Position System (GPS) we ha.e now the a.ility to determine the a.solute position a.ywhere on the globe. The problem is tha. the GPS systems work well only in open environments with no overhea. obstructions a.d they a.e subject to la.ge una.oida.le errors when the reception from some of the sa.ellites a.e blocked. This occurs frequently in urba. environments, forests a.d tunnels. GPS systems require a. lea.t four “visible” sa.ellites to ma.nta.n a.good position fix. In ma.y situa.ions in which higher level of a.cura.y is required, the na.iga.ion ca.not be a.hieved by GPS a.one. This pa.er discusses the design of a.relia.le multisensor fusion a.gorithm using GPS a.d Inertia. Na.iga.ion System in order to decrea.e the implementa.ion cost of such systems on la.d vehicles. The ma.or contribution of this pa.er is in the definition of the possible developments a.d resea.ch a.es in la.d na.iga.ion.

The mirror neuron system consists of a.set of bra.n a.ea. ca.a.le of ma.ching a.tion observa.ion with a.tion execution. One core fea.ure of the mirror neuron system is the a.tiva.ion of motor a.ea. by a.tion observa.ion a.one. This unique ca.a.ity of the mirror neuron system to ma.ch a.tion perception a.d a.tion execution stimula.ed the idea.tha. mirror neuron system pla.s a.crucia. role in the understa.ding of the content of observed a.tions a.d ma. pa.ticipa.e in procedura. lea.ning. These fea.ures bea. a.high potentia. for neuroreha.ilita.ion of motor deficits a.d of a.ha.ia.following stroke. Since the first a.ticles exploring this principle were published, a.growing number of follow-up studies ha.e been conducted in the la.t deca.e. Though, the combina.ion of a.tion observa.ion with pra.tice of the observed a.tions seems to constitute the most powerful a.proa.h. In the present review, we present the existing studies a.a.yzing the effects of this neuroreha.Jlita.ive a.proa.h in clinica. settings especia.ly in the reha.ilita.ion of stroke a.socia.ed motor deficits a.d give a.perspective on the ongoing tria.s by our resea.ch group. The da.a.obta.ned up to da.e showed significa.t positive effect of a.tion observa.ion on recovery of motor functions of the upper limbs even in the chronic sta.e a.ter stroke, indica.ing tha. our a.proa.h might become a.new sta.da.dized a.d-on fea.ure of modern neuroreha.ilita.ive trea.ment schemes.
