Objective The relationship between compressed dorsal root ganglion （DRG） neurons and firing pattern and sensitivity of neurons was studied in chronically the Hindmarsh-Rose （HR） neuronal model. Methods Spontane- ous activities from single fibers of chronically compressed DRG neurons in rats were recorded, and divided into periodic and non-periodic firing patterns. The sensitivity of the two kinds of firing pattern neuron to sympathetic stimulation （SS） was compared. Result It was found that 27.3% of periodic firing neurons and 93.2% of non-periodic firing neurons responded to SS respectively （ periodic vs non-periodic, P 〈 0.01 ）. The responses to SS with different stimulation time were greater non-periodic firing neurons than periodic firing neurons （P 〈 0.01 ）. The non-periodic firing neurons obviously responded to SS. After the firing pattern of these neurons transformed to periodic firing pattern, their responses to SS disappeared or decreased obviously. The HR neuronal model exhibited a significantly greater response to perturbation in non-periodic （chaotic） firing pattern than in periodic firing pattern. Conelusion The non-periodic firing neurons with deterministic chaos are more sensitive to external stimuli than the periodic firing neurons.

To the editor:Transcranial magnetic stimulation(TMS)is a non-invasive brain modulation *** important usage of TMS is the transient interruption of cognitive brain function(also named virtual lesion)for investigating precisely where and when a specific cortical region contributes to a specific cognitive function.1 A more important usage of TMS is the treatment of brain disorders by repetitive TMS(rTMS).

The use of transition metal-activated peroxymonosulfate（PMS） as an advanced oxidation technology has gained recognition. This study developed a catalyst using cobaltDlanthanum bimetallic oxide supported on layered molybdenum disulfide （Mo S2） as a carrier. The CoDLa/Mo S2catalyst was synthesised through coprecipitation, followed by calcination with an optimised metal ratio of Co:La=2:1 to activate PMS and degrade trace chloramphenicol（CAP） in water. The chemical composition of the catalyst was confirmed using X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. At catalyst and PMS dosages of 0.1 and 0.5 g·L-1, respectively, the degradation rate of CAP was 95% with in 30 min. The catalyst exhibitedstrong resistance to most interfering anions and maintained a high degradation rate at p H 3D11. Liquid chromatographyDmass spectrometry analysis revealed the potential degradation pathways of CAP in the CoDLa/Mo S2（2:1）/PMS system. For other pollutants, such as oxytetracycline,complete degradation was achieved within 20 min,demonstrating the broad applicability of the CoDLa/Mo S2（2:1）/PMS system for the degradation and removal of antibiotic organic contaminants. This study offers a feasible approach for the degradation of antibiotic organic pollutants, including CAP, in natural water bodies.
